Chilean Academy of Sciences incorporates Professor Bryna Kra as Foreign Corresponding Member

Last Thursday, May 30, in a public session, the Chilean Academy of Sciences incorporated as Foreign Corresponding Member Professor Bryna Kra, outstanding American mathematician, Professor at Northwestern University, Fellow of the National Academy of Sciences (USA) and President of the American Mathematical Society (AMS).

The induction ceremony was presented by Dr. Servet Martínez, Past President and Fellow of the Academy, and Dr. Alejandro Maass, Corresponding Member; both academicians highlighted the trajectory and significant contributions of the researcher in the field of mathematics, and in particular on ergodic theory.

In the context of her incorporation, Professor Bryna Kra gave a master lecture entitled “Dynamic of the integers”, where she presented her results in relation to the search for patterns in integers through the use of sophisticated tools of ergodic theory.

On the occasion she stated: “I am very honored. It is an extraordinary honor to have been chosen and selected, and I hope to continue our many collaborations with the Chileans, and to return many times (to Chile).”

Professor Kra added that her work in the field of statistics is, in her words, “extremely abstract. In mathematics, applications often arise long after the theory is developed. My work involves understanding the basic properties that all dynamical systems must fulfill, in the hope that someday there will be real applications. Right now, my applications are to other areas of mathematics, which can also seem very abstract.”

She commented that there are many examples where theory has been applied in practice. For example, number theory – developed 100 years ago – is now used in every online transaction made with a credit card.

Professor Bryna Kra is a Ph.D. in Mathematics from Stanford University and the Sarah Rebecca Roland Professor at Northwestern University, USA.

In 2012 she became a fellow of the American Mathematical Society (AMS). In 2016 she was named a Fellow of the American Academy of Arts and Sciences, as well as elected to the National Academy of Sciences in 2019. Kra is currently president of the AMS, for the 2022-2025 term.

Within the many areas covered by the AMS, in the academic’s view, it is rewarding to provide resources for mathematicians who do not have them: “many people are doing research with very little funding; so even a small amount of funding can make a big difference. I’ve spent my time as president trying to provide grants to help them in their careers. In addition, I am working on expanding access to our database, making it easier and more affordable.”

Dr. Kra has been a visiting researcher at prestigious international centers, a speaker at the most important congresses and schools in mathematics, and serves on the committees of the most impactful international journals in her field. She collaborates with the ergodic theory group in Chile, participates in seminars and has written joint papers with researchers from our country.

In addition, she has made important contributions to the convergence of unconventional ergodic averages and to the search for patterns in additive combinatorics. Currently, Professor Kra is also a member of the International Scientific Committee of the Center for Mathematical Modeling (CMM) of the Universidad de Chile.

About her work at this center, the researcher said: “Mathematics is a collaborative science. To advance my work, I have students and collaborators from all over the world, including Chile. The CMM in Chile is one of the ways in which I connect with the rest of the world […]. All mathematics, whether developing theory or finding applications for social problems such as water management or climate change, is interconnected, and this international collaboration is crucial.”
