Prof. Michael R. Douglas will visit the International Center for Mathematical Sciences in Sofia
The famous scientist will give lectures at the Bulgarian Academy of Sciences.
On June 30, 2023, Prof. Michael R. Douglas from Harvard University, CMSA will deliver two lectures in the “Marin Drinov” Hall of the Bulgarian Academy of Sciences. Prof. Douglas is visiting the International Center for Mathematical Sciences (ICMS–Sofia) and giving lectures in the Consortium Distinguished Lecture Series, a joint initiative of the ICMS–Sofia and the Institute of the Mathematical Sciences of the Americas (IMSA) at the University of Miami. This lecture series aims to highlight outstanding recent achievements in Mathematics. The distinguished speakers up to now have been: Don Zagier, Ramanujan International Chair, International Center for Theoretical Physics; Karim Adiprasito, Department of Mathematical Sciences, University of Copenhagen, Denmark; Dennis Gaitsgory, Harvard University; Sergei Gukov, California Institute of Technology; Edward Saff, Vanderbilt University, USA; Maria J. Esteban, Center National de la Recherche Scientifique, Paris, France; Ernesto Lupercio, Cinvestav, Mexico; and Andrés Navas, Universidad de Santiago de Chile.
Michael R. Douglas received his PhD in Physics in 1988 under the supervision of John Schwarz, one of the developers and leading researchers in superstring theory. Douglas is best known for his work in string theory, for the development of matrix models (the first nonperturbative formulations of string theory), for his work on Dirichlet branes and on noncommutative geometry in string theory, and for the development of the statistical approach to string phenomenology. He has influenced the developments of modern mathematics by finding interpretations of branes on the language of derived categories and introducing the theory of stability conditions for categories.
Michael R. Douglas received the 2000 Sackler Prize in theoretical physics and has been a Gordon Moore Visiting Scholar at Caltech, a Louis Michel Visiting Professor at the IHES, and a Clay Mathematics Institute Mathematical Emissary. He was the first permanent professor in the Simons Center for Geometry and Physics. Douglas is a fellow of the American Mathematical Society and a member of the American Physical Society, and has served as the editor of the Journal of High Energy Physics and of Communications in Mathematical Physics.
Prof. Bernard Teissier is visiting the International Center for Mathematical Sciences – Sofia
Prof. Bernard Teissier, Institute Mathématique de Jussieu-Paris Rive Gauche, is visiting the International Center for Mathematical Sciences – Sofia and will deliver a lecture on “Objectivity and Subjectivity in Mathematics” next week.
Prof. Bernard Teissier is a world-renowned mathematician who works in the field of algebraic geometry, singularity theory and commutative algebra. On June 8, 2023, Thursday, from 5:00 p.m. in the “Prof. Marin Drinov” hall of the Bulgarian Academy of Sciences he will give a talk on “Objectivity and Subjectivity in Mathematics”. The event takes place within the framework of the BAS Academic Seminar.
Prof. Teissier is a guest of the program “Increasing research capacity in the field of mathematical sciences” (PIKOM) of the Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences (IMI–BAS) and the International Center for Mathematical Sciences – Sofia (ICMS-Sofia). During his visit, he will work with colleagues from IMI-BAS on Lipshitz geometry of singularities of complex-analytic curves.
In 1967, Bernard Teissier graduated from the Ecole Polytechnique in Paris and the same year he decided to devote himself to mathematics after accidentally attended lectures by Oskar Zariski, one of the fathers of modern algebraic geometry, who later became his mentor. In 1968 Teissier became a PhD student of Heiske Hironaka – author of the theorem for resolution of singularities for which proof Hironaka was awarded the Fields Medal.
In the 1970s, Teissier was a visiting professor at Harvard University. After his return to France he fell under the influence of the famous French mathematician René Thom (Fields Medalist, 1958), who is one of the founders of singularity theory. In 1979, it became Directeur de recherche at the National Center for Scientific Research in France (CNRS). From 1987 to 1999, Teissier was a professor at the École normale supérieure in Paris (ENS). Since 2000, he has been associated with the Mathematical Institute Institute Mathématique de Jussieu-Paris Rive Gauche.
Abstract:
In the first part of the talk, I shall explore the consequences of distinguishing the foundations of meaning and the foundations of truth in mathematical statements, or imagination and rigor as motors of mathematical development. The foundations of meaning can be sought in our largely unconscious perception of the world, which modern cognitive science is exploring.
In the second part, I shall illustrate this by comparing two approaches to understanding mathematical problems: creating appropriate abstract structures, which is exemplified by Galois, Hilbert, Bourbaki and Grothendieck, or creating geometric models where we can use our intuition of space, of which Riemann, Poincaré and Thom were masters. This part requires some basic mathematical knowledge.
Prof. Edward Saff presented the certificates to the Rose and Irving Saff Award laureates
Award in mathematics Rose and Irving Saff was founded by Prof. Edward Saff from Vanderbilt University, Tennessee, USA, who is a foreign member of the Bulgarian Academy of Sciences in memory of his parents.
It is awarded each year to a student in mathematics for high achievements and excellence in mathematics.
In a modest ceremony held at the Institute of Mathematics and Informatics yesterday, May 31, Prof. Saff personally presented the certificates to the winners of the Rose and Irving Saff Award for the past four years. In the past few years, the Award has been awarded, but the ceremony was not held due to the restrictions imposed by the Covid-19 pandemic.
The awardees are:
Maria Pashinska, Faculty of Mathematics and Informatics, Veliko Tarnovo University, winner of the Award for 2019,
Elena Nikolova, Technical University of Sofia, laureate of the Award for 2020,
Plamen Ivanov, Faculty of Mathematics and Informatics, Sofia University “St. Kliment Ohridski”, awarded in 2021 and
Aleksander Prodanov, Faculty of Physics, Sofia University “St. Kliment Ohridski”, awarded in 2022.
Prof. Edward Saff is in Bulgaria to participate in the Sphere packings, coverings, and spherical codes (SPCSC2023) international workshop that ended yesterday. He is a sincere friend of Bulgaria and Bulgarian mathematicians and is planning his next visit to Sofia during the International Conference Mathematics Days in Sofia, which will be held from July 10 to 14 this year.

Luis A. Caffarelli is the 2023 Abel Prize Laureate

The Norwegian Academy of Science and Letters has decided to award the Abel Prize for 2023 to Luis A. Caffarelli of the University of Texas at Austin, USA for his “seminal contributions to regularity theory for nonlinear partial differential equations including free-boundary problems and the Monge–Ampère equation”.
Few other living mathematicians have contributed more to our understanding of partial differential equations than the Argentinian–American Luis Caffarelli. He has introduced ingenious new techniques, shown brilliant geometric insight, and produced many seminal results. Over a period of more than 40 years, he has made groundbreaking contributions to regularity theory. Regularity – or smoothness – of solutions is essential in numerical computations, and absence of regularity is a measure of how wildly nature can behave.
“Caffarelli’s theorems have radically changed our understanding of classes of nonlinear partial differential equations with wide applications. The results are technically virtuous, covering many different areas of mathematics and its applications,” says chair of the Abel Committee Helge Holden.
Caffarelli is an exceptionally prolific mathematician, with more than 130 collaborators and more than 30 PhD students over a period of 50 years.
“Combining brilliant geometric insight with ingenious analytical tools and methods he has had and continues to have an enormous impact on the field,” says Helge Holden.
Luis A. Caffarelli has won numerous awards, among them the Leroy P. Steele Prize for Lifetime Achievement in Mathematics, the Wolf Prize and the Shaw Prize.
The presentation of the Abel Prize to Luis Caffarelli will take place at a formal ceremony to be held on 23 May 2023 in Oslo, Norway.
