Colloquium 2/23: Marcus Webb on “The Freshman’s Dream”

On Monday, February 23rd at 3:30 PM in Math 357, Marcus Webb will talk about “The Freshman’s Dream.” Abstract: Let A be an m by n matrix with entries in some finite field – the integers modulo a prime p, for example. What happens to the kernel of A when we raise each entry to the p’th power? In this talk, we will answer this question and consider its generalization to matrices with entries in a commutative ring of prime characteristic. For such rings, every freshman’s dream is true: (a+b)^p=a^p+b^p, and we will explore some of the remarkable consequences of this equality. (flyer in PDF form)
