Olga Holtz ( Russian Ольга Гольц ; born August 19, 1973 in Chelyabinsk Oblast in the Urals Federal District ) is a Russian mathematician .

Life

Her parents were both programmers. Even as a schoolgirl, the mathematical talent was noticed, so that she came to a high school with a mathematical focus.

Olga Holtz began her studies at the South Ural State University in Chelyabinsk , where she graduated in 1995. In 1996 she moved to Madison (Wisconsin) in the USA. There she received her doctorate in 2000 at the University of Wisconsin with Hans Schneider ( Theorems and Counterexamples on structured matrices ), where she then did research at the Institute for Computer Science. In 2002 she received a research grant from the Alexander von Humboldt Foundation and worked for one year at the Technical University of Berlin with Volker Mehrmann . From 2004 to 2007 Holtz was assistant professor ( Morrey Assistant Professor ) at the University of California, Berkeley , with Alan Weinstein . In November 2006, Olga Holtz became the Sofja Kovalevskaja Prize winner . This gave her the opportunity to carry out a research project for four years with a budget of almost one million euros. She chose the TU Berlin again. In 2008 she received the EMS Prize and was accepted into the Junge Akademie . In 2009 she received the advance professorship at the Technical University of Berlin, and in 2010 an ERC Starting Grant from the European Research Council with a budget of 880,000 euros for five years. In addition to her professorship in Berlin, she is also a professor at Berkeley. In 2009/2010 she was a John von Neumann Fellow at the Institute for Advanced Study . She is a Fellow of the American Mathematical Society .

In addition to mathematics, Holtz has other interests. She loves music, especially Johann Sebastian Bach , and had considered training as a pianist as a profession. She is also an active choir singer and dancer. Since 2007 she has been singing in the Berlin Philharmonic Choir under the artistic director Jörg-Peter Weigle .

In 2013 she directed her first feature film, The Zahir , which was shot in Berkeley. It is inspired by a short story of the same name by Jorge Luis Borges and by Magical Realism and has an obsession with following one's own ideas as a subject.

Her Erdős number is 3.

Services

She is concerned with numerical linear algebra and matrix theory , commutative algebra , computer science (analysis of algorithms , complexity theory ), numerical analysis (such as wavelets and splines , approximation theory ), counting combinatorics (such as algebra of zonotopes ), signal processing (such as compressive sensing ) and probability theory. In the laudation for the EMS Prize 2008, the proof of Newton's inequalities for M-matrices, fundamental work on the evaluation of polynomials in finite arithmetic and the proof that all algorithms based on group theory for fast matrix multiplication are numerically stable were emphasized .
