SUMMARY:Семинар по геометрия на МЦМН
DESCRIPTION:Следващата сбирка на Семинара по геометрия на МЦМН\nще се проведе в сряда\, 7 февруари 2024 г. от 16:00 ч. в зала 403 и онлайн в Zoom: \nДоклад на тема \nIntroduction to curve counting\n\nще изнесе Михаил Школников\, ИМИ – БАН. \n\nZoom link:\n\nhttps://us02web.zoom.us/j/83740034721?pwd=VnBtcVpGUktscHQ4a09jZkNZTURyZz09\n\nAbstract: This talk is intended as a very gentle introduction to the classical subject of enumerative geometry concerned with problems of counting algebraic curves with prescribed properties. In the realm of classical planimetry\, we know that there exists a single circle passing through a collection of three points\, provided that these points are generic. Here “generic” simply means that the points are not collinear\, i.e. don’t belong to the same line but could refer to some other open condition in a different context; the number of points is just right for a problem to be well-stated — there are infinitely many circles passing through any two points and a collection of four points lying on a circle is special. A less trivial example\, which will be considered in detail\, is the question “How many rational cubic curves on the plane pass through a generic collection of eight points?”. “Rational” here means that a curve has a parametrization by rational functions\, and “cubic” refers to a curve defined as a zero locus of a degree three polynomial. The number of points is again chosen just right so that one may expect a non-trivial answer. In the case of real algebraic geometry\, the number of cubics may vary depending on the position of the eight generic points\, and a priori it is even not clear if such curves exist for all configurations. On the other hand\, if we state the same problem over complex numbers the answer becomes definite and independent of the position of the generic points. By an elegant\, yet quite elementary\, topological reasoning we will deduce that this answer is 12. Adapting the same argument in the real case\, we will see that real rational cubics should be counted with signs and the result of this new count becomes a definite -8\, proving in particular that for any generic configuration of eight points on the real plane\, there exist at least eight rational real cubics passing through them.

SUMMARY:Семинар на МЦМН
DESCRIPTION:Дата: 13.02.2024 г.\, 14:00 ч. \nМясто: Зала 403\, ИМИ – БАН \nДокладчик: Jean-Pierre Gazeau (APC\, Université Paris – Cité) \nДоклад: Quantum circuit complexity for light polarisation or complexity with no complex numbers \nДопълнителна информация: https://icms.bg/quantum-circuit-complexity-for-light-polarisation-or-complexity-with-no-complex-number-talk-by-jean-pierre-gazeau/ \nРезюме. I will present a form of quantum circuit complexity that extends to open systems. To illustrate the methodology\, I focus on a basic model where the Hilbert space of states is represented by the Euclidean plane. Specifically\, the investigation is about the dynamics of mixed quantum states as they undergo interactions with a sequence of gates. The approach involves the analysis of sequences of density matrices. Each density matrix evolves within the framework of a Gorini-Kossakowski-Lindblad-Sudarshan (GKLS) process during the time interval between consecutive gates. Notably\, when considering an upper limit for the cost function\, the optimal number of gates follows a power-law relationship.

SUMMARY:Национален семинар по стохастика
DESCRIPTION:Поредната сбирка на \nНационалния семинар по стохастика\nще се проведе на 14 февруари 2024 г. (сряда) от 14:00 часа в зала 503 на ИМИ – БАН. \nДоклад на тема \nComputable inference for generalised Wright-Fisher processes\nще изнесе \nNathan Judd (University of Warwick\, UK). \nАбстракт.In this talk\, we will introduce a class of [0\,1]-valued Markov processes with jumps that\, as signals in hidden Markov models\, admits a computable (exact) filter. By computable filter we mean that each filtering distribution\, i.e.\, the law of the signal at a time t given the data up to time t\, is explicitly and exactly available as a finite mixture of Dirichlet distributions. We exploit the tractability of the Wright-Fisher diffusion\, in particular\, its infinite-sum transition function and its dual process\, as a base to construct a generalised version thereof\, for which we derive the (exact\, predictive and smoothing) filters of the associated hidden Markov model. In addition\, we construct an exact sampling scheme to draw samples from the transition functions of this process. \n\n

DESCRIPTION:Следващата сбирка на Семинара по геометрия на МЦМН\nще се проведе в сряда\, 14 февруари 2024 г. от 16:00 ч. в зала 403 и онлайн в Zoom: \nДоклад на тема \nRefined curve counting\n\nще изнесе Михаил Школников\, ИМИ – БАН. \n\nZoom link:\n\nhttps://us02web.zoom.us/j/83740034721?pwd=VnBtcVpGUktscHQ4a09jZkNZTURyZz09\n\nAbstract: Refining an enumerative problem upgrades the numerical solution to a polynomial so that its specialization gives the original number. A prototypical example of such refinement arises in the tropical curve counting from replacing Mikhalkin multiplicities\, corresponding to counting complex curves\, with Block-Goettsche multiplicities. I will speak about the invariance of this count and its various interpretations.

SUMMARY:Научен семинар на ВНЗ "Информационно моделиране"
DESCRIPTION:На 22 февруари (четвъртък)\, от 14 ч.\, в зала 503 на ИМИ-БАН\,\nще се проведе научен семинар на ВНЗ “Информационно моделиране”.\nДоклад на тема: \nИнтегриране на релационни данни и неструктурирани големи данни с подобен на SQL функционален език\nще изнесе гл. ас. д-р Боян Колев. \nРезюме: Polystore systems have been proposed to provide integrated access to multiple\, heterogeneous data stores through a single query engine. In particular\, much attention is being paid on the integration of relational data with unstructured big data typically stored in HDFS. One typical legacy solution is to use a relational query engine that allows SQL-like queries to retrieve data from HDFS\, which requires the system to provide a relational view of the unstructured data and hence is not always feasible. This talk presents an approach to overcome such limitations through a functional SQL-like query language that can integrate data retrieved from different data stores and take full advantage of the functionality of the underlying data processing frameworks by allowing the ad hoc usage of user-defined map/filter/reduce operators in combination with traditional SQL statements. Furthermore\, the query language allows for optimization by enabling subquery rewriting so that filter conditions can be pushed inside and executed at the data store as early as possible. The approach is validated with two data stores (an SQL database and the parallel data processing framework Apache Spark that operates on a distributed dataset) and a representative query that demonstrates the usability of the query language and evaluates the benefits from query optimization. \nЗа дистанционно включване: \nJoin Zoom Meeting\nhttps://us02web.zoom.us/j/81054245812?pwd=NDltMlpjbXRnUEZGeTRuZkt2Um9SZz09 \nMeeting ID: 810 5424 5812\nPasscode: 286884

SUMMARY:Семинар "Алгебра и логика"
DESCRIPTION:На 23 февруари 2024 г. (петък) от 13:00 часа ще се проведе дистанционно заседание на семинара по „Алгебра и логика”. \nДоклад на тема: \nInvariant subalgebras of the rational Cherednik algebra\nще изнесе \nNiall Hird (University of Glasgow\, UK). \nАбстракт. The rational Cherednik algebra is a degeneration of the double affine Hecke algebra and an object of interest to many representation theorists\, it also has strong connections to integrable systems. In my talk I will discuss two subalgebras that arise from considering the invariants of the action of reductive subgroups of the special linear group. In particular we will examine the centres of these invariant subalgebras and compare with the algebra of invariants of the centre of the entire rational Cherednik algebra under the same groups. These subalgebras arise naturally in the study of rational Cherednik algebras\, one of which is the Dunkl angular momentum algebra and the other is generated by all degree zero elements. \nЛинк към Zoom-стаята на семинара:\nhttps://us02web.zoom.us/j/85137375021?pwd=RE5QczdFTE1xL1R6MnI2b1lkcGczQT09 \n\n\n\nОт секция „Алгебра и логика” на ИМИ – БАН\nhttp://www.math.bas.bg/algebra/seminarAiL/\n============================== =====================

SUMMARY:Семинар по геометрия на МЦМН
DESCRIPTION:Следващата сбирка на Семинара по геометрия на МЦМН\nще се проведе в сряда\, 28 февруари 2024 г. от 16:00 ч. в зала 403 и онлайн в Zoom: \nДоклад на тема \nLinear embeddings of complex Grassmannians\n\nще изнесе Иван Пенков\, Constructor University Bremen. \n\nZoom link:\n\nhttps://us02web.zoom.us/j/83740034721?pwd=VnBtcVpGUktscHQ4a09jZkNZTURyZz09\n\nAbstract: A linear embedding of Grassmannians\, one of which could possibly be isotropic\, is an embedding which respects the generators of Picard groups. Several years ago A.S. Tikhomirov and I classified such embeddings when both Grassmannians are simultaneously usual Grassmannians or isotropic Grassmannians of the same type(orthogonal or symplectic). In this talk I will discuss also the mixed case. A classification as above has an application to the classification of infinite-dimensional linear ind-Grassmannians\, and I shall  briefly explain this at the end of the talk.
