Dennis Parnell Sullivan is an American mathematician most famous for his ground-breaking work on topology and dynamical systems, two fields in which ideas about geometric structure play a central role. A charismatic and lively member of the mathematics community, he has found deep connections between a dazzling variety of areas of mathematics.

In its citation, the Norwegian Academy of Science and Letters, the organization that administers the Abel, said Prof. Sullivan was honoured “for his groundbreaking contributions to topology in its broadest sense, and in particular its algebraic, geometric and dynamical aspects.”

Among his significant results in topology is his proof of the Adams conjecture, and in dynamical systems he proved that rational maps have no wandering domains, solving a 60-year-old conjecture. His insistent probing for fundamental understanding, and his capacity to see analogues between diverse areas of mathematics and build bridges between them, has forever changed the field. Dennis P. Sullivan has won numerous awards, among them the Steele Prize, the 2010 Wolf Prize in Mathematics and the 2014 Balzan Prize for Mathematics. He is also a fellow of the American Mathematical Society.

Ulrike Tillmann, a mathematician at the University of Oxford who served on the Abel committee, said that given Dr Sullivan’s “absolutely fantastic work” in both algebraic topology and dynamical systems, “it was a very easy decision to make.”

The prize is accompanied by 7.5 million Norwegian kroner, or about $850,000.

“Mathematics is truly a passion that provides a never-ending stream of curiosities and puzzles, and I’ve been privileged to spend each day of my professional life in the company of the many talented colleagues and students who have conspired with me to tackle these challenges so that we might better understand the rules of the universe. This award is as much a testament to their hard work and insights as it is a gift to me.” Prof. Sullivan says to the CUNY Graduate Center’s website.

The Norwegian Academy of Science and Letters, on behalf of the Ministry of Education, awards the Abel Prize, and it will be officially presented by His Majesty King Harald at a ceremony in Oslo, Norway on May 24.

The event will be streamed live on The Abel Prize YouTube Channel.

90th anniversary of the birth of Professor Blagovest Sendov

February 8, 2022, marks the 90th anniversary of the birth of Blagovest Sendov. He passed away on January 19, 2020, shortly before reaching the age of 88.

The Institute of Mathematics and Informatics will commemorate the 90th anniversary of the birth of Prof. Sendov with the following talk by Edward Saff from Vanderbilt University, USA

 Sampling with Minimal Energy:
A talk in commemoration of B. Sendov’s 90th birth date.

This lecture is a part of the Consortium Distinguished Lecture series, organized jointly by the Institute of Mathematical Sciences of the Americas at the University of Miami and the International Center for Mathematical Sciences at IMI-BAS, whose first director was professor Sendov. The event will be held online via Zoom on February 9, 2022, at 6 o’clock PM (EEST, Sofia time).

Professor Edward Saff is a distinguished specialist in the theory of approximations, editor-in-chief of Springer’s journal Constructive Approximation and Director of the Center for Constructive Approximations at Vanderbilt University. He has been a foreign member of BAS since 2013. He has a long and productive relationship with Bulgaria and the Institute of Mathematics and Informatics. In 2014, he established the annual Rose and Irving Saff Mathematics Award, awarded to a Bulgarian mathematics student for outstanding achievement and excellence in mathematics.

Prof. Sendov is a world-famous Bulgarian mathematician, a dedicated innovator educator, a prominent statesman and a respected public figure.

He graduated from Sofia University “St. Kliment Ohridski”, and later specialized in computational mathematics at Moscow State University. Since 1968 he had been a professor of computational mathematics at Sofia University.

Prof. Sendov was the youngest doctor of sciences, the youngest professor and the youngest rector of Sofia University. He was one of the brightest figures in the scientific life of Bulgaria. His scientific work was of great impression with its content, diversity and productivity until the very end of his life. He was the author of over 200 scientific publications, several monographs, numerous textbooks and popular articles. Prof. Sendov was one of the pioneers of informatics in Bulgaria and together with prof. Lyubomir Iliev has a fundamental contribution to its complex development in the country. He was a key figure in the team that created the first Bulgarian digital-electronic computer “Vitosha” and one of the world’s first electronic calculators “Elka 6521”.

Prof. Sendov was a courageous reformer of the educational system at all levels. In 1970, as a Dean of the Faculty of Mathematics at Sofia University, he introduced the three-level form of education (Bachelor, Master and PhD). It was not until twenty-five years later that such an organization of university education was adopted throughout the European Union.

Prof. Sendov is a prominent statesman and public figure. He was Rector of Sofia University, Chairman of the Bulgarian Academy of Sciences, Chairman of the National Assembly of the Republic of Bulgaria and Ambassador of Bulgaria to Japan.
