Tikhonov, Sergey

ICREA Research Professor at CRM (Centre de Recerca Matemàtica). Experimental Sciences & Mathematics

I was born in Russia in 1976. I graduated from the Lomonosov Moscow State University in 1999 and obtained my PhD in Mathematics from MSU in 2003.

2004-2006: Marie Curie Fellow at the Centre de Recerca Matemàtica, Barcelona.

2006-2008: Post-doctoral Fellow at the Scuola Normale Superiore, Pisa.

2008-September 2012: ICREA Researcher, CRM

From September 2012, I am an ICREA Research Professor at the Centre de Recerca Matemàtica.

2009: ISAAC Award.

2013: Humboldt Research Fellowship for Experienced Researchers.


Research Interests

Mostly my research deals with Fourier Analysis and Approximation Theory. Particularly, I study the relationship between "smoothness" of a function and the possibility to approximate or to represent this function by a sum of "simple" functions. The case when "simple" functions have wave structure is of special interest.
