Nikhil Srivastava Wins Michael And Sheila Held Prize

Nikhil Srivastava, an Indian mathematician, has been named winner of the prestigious 2021 Michael and Sheila Held Prize along with two others for solving long-standing questions on the Kadison-Singer problem and on Ramanujan graphs.
Srivastava from the University of California, Berkeley, Adam Marcus, the Ecole polytechnique federale de Lausanne (EPFL) and Daniel Alan Spielman from Yale University will receive the 2021 Michael and Sheila Held Prize.
Srivastava, Marcus and Spielman solved long-standing questions on the Kadison-Singer problem and on Ramanujan graphs, and in the process uncovered a deep new connection between linear algebra, geometry of polynomials, and graph.
The Michael and Sheila Held Prize is presented annually and honours outstanding, innovative, creative, and influential research in the areas of combinatorial and discrete optimisation, or related parts of computer science, such as the design and analysis of algorithms and complexity theory.
The prize was established in 2017 by the bequest of Michael and Sheila Held.
The award is given by National Academy of sciences, USA.
