Counterexamples related to high-frequency oscillation of Poisson's kernel

Research output: Contribution to journalArticle

Abstract

Let {Mathematical expression} where a is a smooth periodic matrix and L0 is the homogenized operator corresponding to the family (Lε). Let D be a nice domain, and let Pε(x, y), P0(x, y) be the Poisson kernels associated with Lε and L0. We show that in general Pε(x, ·) does not converge strongly to P0(x, ·) in Lp, by exhibiting two counterexamples. This result has the following implication in the theory of boundary control of distributed systems: if, with z given, uε(x) = ∫ Pε(x, y)g(y) and u0(x) = ∫P0(x,y)g(y), then, in general,.
