SoM is proud to announce that our new faculty member, Richard A. Duke Assistant Professor Vesselin Dimitrov is the laureate of the 2023 IMI Mathematics Prize. The Prize is awarded every three years to a Bulgarian mathematician under the age of 40 for high achievements in the field of mathematics. More information can be found in the article published in English at:

The Prize was awarded by the President of Republic of Bulgaria during the opening of the International Conference “Mathematics Days in Sofia 2023”, https://mds.math.bas.bg*From the IMI article:*

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.

#### About Vesselin Dimitrov

Prof. Dimitrov is interested in the small-scale distribution properties of Galois orbits of algebraic points, and he has worked to develop new arithmetic algebraization theorems for formal power and Dirichlet series with an eye to applications to transcendence and to Dirichlet L-functions.

*From the IMI article:*

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.
