Analytic semigroups generated in L^p by elliptic operators with high order degeneracy at the boundary


Abstract


Given a regular bounded domain, we show that an elliptic operator whose diffusion coefficients degenerate at the boundary at least as the square of the distance from the boundary, endowed with a suitable domain, generates an analytic semigroup in L^p, 1<p<\infty. The proof relies on the discussion of the model case of the half-space and the derivation of the main result via local charts.
