SUMMARY:Семинар на МЦМН
DESCRIPTION:Дата и място: вторник\, 9 юни 2026 г.\, 13:00\, зала 403\, ИМИ-БАН.\nЛектор: Azur Đonlagić (Université Paris-Saclay\nЗаглавие: Brauer-Manin Obstructions for Homogeneous Spaces \nРезюме: In this talk\, we introduce Brauer-Manin obstructions to the Hasse principle and to weak/strong approximation of adelic points on varieties over a global field. We also define variants of these obstructions well-suited for the study of rational points on homogeneous spaces of affine algebraic groups. \nWe then state the main questions considered in this theory and give an account of some developments\, including the speaker’s recent work. Finally\, we present briefly the main tools and ideas used in the theory\, such as arithmetic duality theorems\, highlighting the difficulties which appear in positive characteristic.\n\n\nЗа допълнителна информация:\nhttps://icms.bg/brauer-manin-obstructions-for-homogeneous-spaces/\nhttps://icms.bg/category/icms-seminar/

SUMMARY:Национален семинар по стохастика
DESCRIPTION:Поредната сбирка на \nНационалния семинар по стохастика\nще се проведе на 9 юни 2026 г. (вторник) от 14:00 часа в зала 503 на ИМИ – БАН. \nДоклад на тема \nModified percolation models on lattice graphs\nще изнесе \nViktor Stoyanov (University of Warwick). \nAbstract: We consider modified percolation models on the first quadrant of \(Z^2\)\, where many of the key tools from standard percolation on \(Z^2\) fail\, such as translational invariance. I will begin by defining the standard percolation model on \(Z^d\)\, giving an overview of what is known\, and then give some results which we prove for the first quadrant of \(Z^2\). In the second part of the talk\, I will discuss an anisotropic percolation model on the first quadrant\, with one of the two directions being ‘preferable’\, and show a partial result concerning the strict monotonicity of the connectivity function\, conjectured by de Lima and Procacci (2004). This is based on work completed as part of my Masters’ dissertation project\, supervised by Daniel Valesin (University of Warwick). \nПовече информация за доклада можете да намерите на страницата на семинара:\nhttp://www.math.bas.bg/~statlab/NSPS/ \n

SUMMARY:Национален колоквиум по математика
DESCRIPTION:СЪЮЗ НА МАТЕМАТИЦИТЕ В БЪЛГАРИЯ\n\nИНСТИТУТ ПО МАТЕМАТИКА И ИНФОРМАТИКА – БАН \n\n\n\nНАЦИОНАЛЕН КОЛОКВИУМ ПО МАТЕМАТИКА\n\n​Поредната сбирка на Колоквиума ще се състои на 17 юни 2026 г. (сряда)  от 16:15 часа в Заседателната зала на ИМИ – БАН.\nДоклад на тема:\n\nGerd Faltings: From the Mordell Conjecture to the Abel Prize\nще изнесе д-р Александрос Константину\,\nМЦМН\, Институт по матем​атика и информатика\, Българска академия на науките. \n\n\n\nРезюме. Faltings’ proof of the Mordell conjecture is one of the landmark results of twentieth-century mathematics. It states that a smooth projective curve of genus at least 2 over the rationals has only finitely many rational points. For this work\, Faltings received the Fields Medal in 1986. In 2026 he was awarded the Abel Prize\, whose citation described him as “a towering figure in arithmetic geometry”. He is one of only eight mathematicians to have received both honours. \nThis talk gives an accessible introduction to the mathematics surrounding this theorem. The central question is classical: when does a polynomial equation have rational solutions? Arithmetic geometry reframes this as the study of rational points on curves\, and the behaviour of these points turns out to depend strongly on the geometry of the curve. The genus is the organising principle\, with conics\, elliptic curves\, and curves of genus at least 2 behaving in fundamentally different ways. \nWe will explain why Faltings’ theorem marked a decisive break from what came before\, and why it remains a central theorem in modern number theory.
