Fourth Annual Conference “Women in Mathematics in South-Eastern Europe”

The International Center for Mathematical Sciences (ICMS-Sofia and the Institute of the Mathematical Sciences of the Americas at the University of Miami (IMSA) are organizing the Fourth International Conference “Women in Mathematics in South-Eastern Europe”. The conference will be held on December 18 to 20, 2023 and will be hosted by the Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences, Sofia.

The initiative Women in Mathematics of South-Eastern Europe, aiming at promoting the role of female mathematicians, started in Dec 2020, when the inaugural conference took place. Even then, the organizers stated their intention to turn the scientific forum into a prestigious annual event. A special distinguished guest of the inaugural conference was Prof. Mina Teicher from the Department of Mathematics and Gonda Brain Research Center, Bar-Ilan University, Israel, Director of Emmy Noether Institute for Mathematics.

One of the main goals of the conference organizers is to create new long-term collaborations between mathematicians in South-Eastern Europe. They expect that through participation women mathematicians will attract the attention of young researchers and researchers from less-favoured countries.

The event is held with the support of the Bulgarian Research Program Enhancing the Research Capacity in Mathematical Sciences (PIKOM) and Simons Foundation.

The official opening of the conference will take place on December 18, 2023 at 1:30 p.m. in the Hall 403 of the Institute of Mathematics and Informatics.

Information about all speakers, as well as titles and abstracts of their reports, can be found here

Tenth Vasil A. Popov Prize

The Tenth Vasil A. Popov Prize was awarded to Matthew Colbrook, Assistant Professor at the University of Cambridge.

Matthew (Matt) was recognized for his outstanding contributions to approximation theory, particularly his work on the approximation of spectral properties of operators in infinite-dimensional spaces and the approximation power and trainability of neural networks. Computing approximations of spectra in infinite dimensions has been a significant challenge for mathematicians since the 1950s. Matt has introduced new algorithms that converge and come with explicit approximation guarantees. He has also developed a myriad of techniques yielding optimal approximation results for different spectral properties of operators, classifying when this can and cannot be done in the Solvability Complexity Index Hierarchy, and solving other open problems such as approximating generic spectral measures, geometric spectra, and (data-driven) Koopman operators in dynamical systems.

Parallel to this work, Matt has contributed significantly to the problem of approximation power and trainability of neural networks. For example, in a paper published in Proceedings of the National Academy of Sciences (PNAS), Matt and his collaborators have shown that there are problems where stable and accurate neural networks exist, yet no training algorithm can produce such a network.

The “Vasil A. Popov” Prize is presented in honour of the Bulgarian mathematician Vasil A. Popov (1942-1990), who is best known for his contribution to the Theory of Approximations.

The prize was awarded for the first time in 1995. The prize, which consists of an engraved marble statuette and a cash prize, is awarded every three years for outstanding research contributions in the field in which Vasil Popov worked. Winners of the award can be young scientists – these are individuals who have received their doctorate in the last six years.

The Tenth Vasil A. Popov Prize, which consists of a pyramid trophy and a cash award of 2000 euros, was presented to Matthew by Albert Cohen of Sorbonne Université, Chair of the Popov Prize Selection Committee. The other members of the Selection Committee are Emmanuel Candes, Wolfgang Dahmen, Karlheinz Grochenig, Pencho Petrushev, Peter Oswald, and Vilmos Totik.

Vesselin Dimitrov is the laureate of the 2023 IMI Mathematics Prize

The Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences is proud to announce Vesselin Dimitrov to be the laureate of the IMI Mathematics Prize for the year 2023 for excellent achievements in Mathematics.

He receives this recognition for his outstanding contributions to number theory and Diophantine geometry.

The IMI award for 2023 was presented to Dr. Vesselin Dimitrov on July 10, 2023, during the opening of the International Conference “Mathematics Days in Sofia 2023”. The prize was presented by Prof. Julian Revalski, President of the Bulgarian Academy of Sciences and Chairman of the Prize Committee, and was personally delivered by the President of the Republic of Bulgaria, Rumen Radev.

Vesselin Dimitrov was born in Sofia in 1986. He graduated from the National Gymnasium of Natural Sciences and Mathematics “Academician Lyubomir Chakalov”. In 2003, he was chosen to represent Bulgaria in the prestigious six-week summer school of the Massachusetts Institute of Technology – Research Science Institute (RSI). In 2005, he participated in the International Mathematics Olympiad, where he won a silver medal.

Dr. Dimitrov continued his education at Harvard University, where he received his bachelor’s degree in 2010 with a thesis under the supervision of Prof. Barry Mazur. He received his MA (2014) and PhD (2017) from Yale University. His academic supervisor was Prof. Alexander Goncharov. Dr. Dimitrov is currently a member of the Institute of Advanced Study at Princeton and an associate professor at the Georgia Institute of Technology, USA. In 2022 Dr. Dimitrov was awarded the Oberwolfach Prize for “his outstanding contribution to number theory and Diophantine geometry” and with the David Gross Prize (which he shared with Ziyang Gao).

Vesselin Dimitrov works in the field of number theory, Diophantine geometry, and related problems from algebraic geometry, representation theory and harmonic analysis. He proved two famous and very difficult conjectures from the 1970s: The Schinzel-Zassenhaus conjecture for algebraic units close to the unit circle and the “unbounded denominators” conjecture, which concerns incongruent modular forms and which he proved together with Yunqing Tang and Frank Calageri. Another significant contribution of Vesselin Dimitrov, Ziyang Gao and Philipp Habegger is the proof of a uniform bound for the number of rational points of a curve X of genus g>1, which depends only on g and the rank of the Mordell-Weil group of the Jacobian of X.

About the Prize

For the first time, the Prize was awarded in 2014 to Martin Kassabov, a Professor at the University of Cornell, USA. In 2017, during the International Conference Mathematics Days in Sofia, the prestigious award was presented to Kiril Dachev, professor of mathematics at Purdue University, USA. The first woman recipient of the IMI Award is Greta Panova, associate professor at the University of Southern California, USA, who received the award in 2020. More about the laureates read here.

The IMI award is a metal statuette, accompanied by a diploma and a cash prize. Funds for the premium are raised through donations. Details about the Prize and the nominations procedure can be found in the Statute of the Prize.
