We will have our first talk of the semester next week, 02/18, by Cody Hutcheson. It will be on Wednesday at 11:00 am in GP 234. Title: Relating first and second-order layer potentials Abstract: We consider divergence form elliptic operators of the form L=÷AL= – \div A \nabla on \R^{1+n}_+, n \geq 2, where AA is a (1+n)×(1+n)(1+n) \times (1+n) elliptic, complex, λ\lambda-independent matrix. We show that the single and double layer potentials constructed using so called “first order” methods are in...
