Abstract
Let ℙ=(P t)t<0 be a semigroup of kernel and letm be an excessive reference measure for ℙ. In this work we prove that ℙ ism-basic if and only if everym.a.e. finite purely excessive function is represented by a unique exit law for ℙ. In this case we deduce some applications about natural densities, energie functionnal and invariant functions for the time-space semigroup of ℙ.
