RIVERSIDE, Calif. — Vyjayanthi Chari, a professor of mathematics at the University of California, Riverside, has been highlighted twice in a list of most highly cited articles published in the International Mathematics Research Notices (as of February 1, 2015). Chari’s research paper “Characters and blocks for finite-dimensional representations of quantum affine algebras” (along with a coauthor) ranked 3, while her paper “Braid group actions and tensor products” ranked 21.

“The International Mathematics Research Notices is one of the top math journals; in 2013 its impact factor placed it 38th out of 299 math journals,” said Cindy Larive, the divisional dean for chemistry, mathematics and physics & astronomy in the College of Natural and Agricultural Sciences. “It is especially impressive that Dr. Chari has two articles on the most-cited list, a strong indicator of the impact of her research.”

Chari received her doctoral degree in mathematics at the University of Bombay (now the University of Mumbai), India, in 1988, after which she was a fellow at the Tata Institute of Fundamental Research, Mumbai. She joined UC Riverside in 1991.

Chari is an expert in representation theory, a fundamental area of mathematics used to understand abstract algebraic ideas by representing them as matrices.  It both uses and has a profound impact on many areas of modern mathematics, and plays an important role in physics where it is used to understand the nature’s symmetries.

“My work is in the representation theory of affine Lie algebras; these are infinite-dimensional objects and how they manifest themselves in finite-dimensional objects,” Chari said.  “This is a very abstract area of mathematics but my graduate students and I have found that using the power of sophisticated computer programs provides deep insight into the theory.”

Chari has held several visiting appointments in her long career.  She was an invited senior participant at the Mittag-Leffler Institute, Sweden; an invited professor at the University of Cologne, Germany; an invited professor at Paris 7, France; an invited research fellow at Brown University, RI; and an invited senior participant at Hausdorff Research Institute for Mathematics, Bonn, Germany.  Later this year, she will be a visiting professor at the University of Rome Tor Vergata, Italy, where she will give a set of advanced lectures on her work.

Currently, she is the editor of the Pacific Journal of Mathematics and Algebras and Representation Theory.  She is the author of nearly 75 research papers, a book, and several edited volumes of conference proceedings.
