Sharp estimates are given for the constants appearing in both the smoothing effect of general self-adjoint contraction semi-groups and uniform estimates for the linear heat equation. The last estimate is used to prove rather sharp global existence results for some nonlinear perturbations and suitabl
## Abstract The norm of the inverse operator of ϵ__A + B__ ‐ λ__I__ between the Besov spaces __B__, ∞ (Ω) and __B^t^∞,∞__(Ω) is estimated, where __A__ and __B__ are uniformly elliptic operators with smooth coefficients and Dirichlet boundary conditions, __A__ is of order 2__m, B__ of order 2__m, m
