摘要：

We investigate the Laplacian Delta on a smooth bounded open set Omega subset of R-n with Wentzell-Robin boundary condition betau + partial derivativeu/partial derivativev + Deltau = 0 on the boundary Gamma. Under the assumption beta is an element of C(Gamma) with beta greater than or equal to 0, we prove that Delta generates a differentiable positive contraction semigroup on C(Omega) and study some monotonicity properties and the asymptotic behaviour.
