Relative Rank and Regularity
Tamar Ziegler
11:15am|Simonyi 101 and Remote Access

The notion of Schmidt rank/strength for a collection of m polynomials plays an important role in additive combinatorics, number theory and commutative algebra; high rank collections of polynomials are “psuedorandom”.  An arbitrary collection of...
