Title: Random algebraic technique and its application

Abstract: Probabilistic method, pioneered by Erdos, is a non-constructive method for proving the existence of a prescribed mathematical structure. Using the magic word "choose randomly", one can, for example, provide a lower bound for the Ramsey number. However, the method fails on certain problems, and the rescue is to choose randomly and "wisely". In this talk, I will explain the random algebraic technique based on Random algebraic construction of extremal graphs by Boris Bukh. If time permits, I will touch on the idea behind the construction for the rational exponent problem recently solved by Boris Bukh and David Conlon.
