A random walk on expanders, despite its strong underlying correlations, poses extremely useful pseudorandom properties. The expander hitting property and the expander Chernoff are two such classic examples. That is, the AND function and certain...

The study of linear spaces of matrices arises naturally (and independently) in many different areas of mathematics and computer science.  In this survey talk, I will describe some of these motivations, and state and prove some (old and new)...

Every multivariate polynomial P(x_1,...,x_n) can be written as a sum of monomials, i.e. a sum of products of variables and field constants.  In general, the size of such an expression is the number of monomials that have a non-zero coefficient in P...
