## Greta Panova, University of Southern California, is the winner of the IMI prize for 2020

Greta Panova, associate professor at the University of Southern California, is the recipient of the IMI Prize for 2020.

Greta Panova was born in Sofia. She graduated from the National High-School of Mathematics and Natural Sciences in Sofia “Acad. Lyubomir Chakalov”. As a high-school student, she participated in three International Math Olympiads (1999 in Romania, 2000 in South Korea, 2001 in the USA) and won two silver and one gold medal.

She graduated from the Massachusetts Institute of Technology in 2005 with a Bachelor’s degree, received a Master’s degree from the University of California Berkeley in 2006, and finished her Ph.D. at Harvard in 2011 under the supervision of Richard Stanley.

In 2011, Greta Panova received a Simons Postdoctoral Fellowship at the University of California Los Angeles, intermittently she was also a postdoc at the Mathematical Sciences Research Institute (Berkeley) in 2012. In 2014 she became an Assistant Professor at the University of Pennsylvania (Penn), promoted to Associate Professor with tenure in 2018. Since 2018, she has been an Associate Professor at the University of Southern California. In 2017-2018 she was a von Neumann Fellow at the Institute for Advanced Study in Princeton. She has also held invited Visiting Professorship positions at Institute Henry Poincare (Paris) in 2017, Simons Institute for the Theory of Computing (Berkeley) in 2018 and Mittag-Leffler Institute (Stockholm) in 2020.

Throughout her studies and career, she has been a recipient of National Science Foundation awards, research fellowships, and other awards, including a third prize at the Putnam competition as an undergraduate and the best student paper award at the Formal Power Series and Algebraic Combinatorics Conference (Reykjavik, 2011). Besides the visiting positions, she has been a plenary speaker at the Formal Power Series and Algebraic Combinatorics conference (London, 2017), Algebraic and Enumerative Combinatorics in Okayama conference (Japan, 2018), Graduate Combinatorics Conference at Max-Planck Institute in Leipzig (Germany, 2019) and several regional Combinatorics conferences.

Greta Panova works in the area of Algebraic Combinatorics and its applications in Computational Complexity Theory, Probability, and Statistical Mechanics. She has about 40 papers, among them publications in the Journal of the AMS, Advances in Mathematics, Annals of Probability. Many of results concern representation-theoretic multiplicities (notably the Kronecker coefficients of the symmetric group) and their use in the Geometric Complexity Theory for the study of computational lower and the separation of computational complexity classes, in particular disproving some of the main conjectures in the approach to proving the algebraic version of P vs NP. She has also applied symmetric function theory and other algebraic and combinatorial tools to reveal the limiting probabilistic behavior of dimer models in Statistical Mechanics.

The IMI Prize will be presented during the International Conference “Mathematics Days of in Sofia” in 2021.

## 14 March – the International Day of Mathematics

The International Day of Mathematics (IDM) is a worldwide celebration. Each year on March 14 all countries will be invited to participate through activities for both students and the general public in schools, museums, libraries, and other spaces.

March 14 was chosen as the date for the IDM because it was already celebrated in many countries as Pi Day, based on the fact that some countries write it as 3/14 and the mathematical constant π is approximately 3.14. The IDM celebration expands Pi Day to include the whole spectrum of mathematics.

Every year IDM will announce a new theme to flavor the celebration, spark creativity and bring light to connections between mathematics and all sorts of fields, concepts, and ideas.

The theme for 2020 is **Mathematics is Everywhere****. **For more information visit https://everywhere.idm314.org/.

The International Day of Mathematics project is led by the International Mathematical Union with the support of numerous international and regional organizations from all over the world. It was proclaimed by UNESCO on the 40th session of the General Conference, November 26, 2019. The first celebration will be held tomorrow – March 14, 2020.

The IDM website is the main hub for the International Day of Mathematics, online at www.idm314.org.

## International Center for Mathematical Sciences – Sofia at the Institute of Mathematics and Informatics organizes educational workshop on Hodge Theory and Local Systems

In the period March 3-5, 2020, the newly established International Center for Mathematical Sciences – Sofia (ICMS-Sofia) and the Institute of Mathematics and Informatics of the Bulgarian Academy of Sciences are organizing a series of lectures on Hodge theory and local systems. The goal of this workshop is to introduce a new cutting edge area in modern Mathematics.

The main speaker will be Prof. Carlos Simpson, CNRS, Université Côte d’Azur, Nice.

Other lecturers will be Prof. Alexander Efimov (Steklov Mathematical Institute of the Russian Academy of Sciences), Prof. Ludmil Katzarkov (University of Miami, USA; Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences; National Research University Higher School of Economics, Russian Federation), Prof. Viсtor Przyjalkowski (Steklov Mathematical Institute of the Russian Academy of Sciences and International Laboratory of Mirror Symmetry and Automorphic Forms, National Research University Higher School of Economic Moscow), Prof. Dmitry Kaledin (Steklov Mathematical Institute of the Russian Academy of Sciences and National Research University Higher School of Economics, Russian Federation).

The Workshop “Hodge Theory and Local Systems” is the first event at ICMS-Sofia. The purpose of this new center, supported by the Bulgarian Government, is popularizing and developing cutting edge science, and connecting the young Bulgarian scientists with the world’s leading researchers. More workshops will follow.

## Mathematics Days in Sofia – MDS 2020

The conference is organized by the Institute of Mathematics and Informatics of the Bulgarian Academy of Sciences in collaboration with the Union of the Bulgarian Mathematicians and the Faculty of Mathematics and Informatics of Sofia University.

One of the main goals of the conference Mathematics Days in Sofia (MDS) is to bring together Bulgarian mathematicians and computer scientists working all over the world. In this way, the event will enrich the relations between the mathematicians working in Bulgaria and the Bulgarian mathematical diaspora.

The first edition of MDS was held in 2014 at the initiative of a number of prominent Bulgarian mathematicians working in Bulgaria and abroad and attended by more than 300 participants from all over the world. The second conference was organized in 2017 thus making MDS a traditional meeting of Bulgarian mathematicians working in Bulgaria and abroad with their colleagues from prestigious scientific centers all over the world.

The purpose of this event is to present the latest scientific achievements in the field of Mathematics and Informatics.
