The Calderon projector in boundary value problems

Karthik Vasu (UIUC)

Abstract: Usually elliptic operators on manifolds with boundary are not Fredholm without any restriction. When some boundary conditions are imposed it does become Fredholm. The goal will be to "parametrize" the solutions using boundary values. The Calderon projector will be a useful tool in determining which boundary conditions are Fredholm and in finding the index.

Towards Splitting $BP<2> ⋀ BP<2>$ at Odd Primes

Liz Tatum (UIUC Math)

Abstract: In the 1980s, Mahowald and Kane used Brown-Gitler spectra to construct splittings of $bo ⋀ bo$ and $l ⋀ l$. These splittings helped make it feasible to do computations using the $bo$- and $l$-based Adams spectral sequences. I will discuss progress towards an analogous splitting for $BP<2> ⋀ BP<2>$ at odd primes.
