The semigroup generated by the Dirichlet Laplacian of fractional order


الملخص بالإنكليزية

In the whole space $mathbb R^d$, linear estimates for heat semi-group in Besov spaces are well established, which are estimates of $L^p$-$L^q$ type, maximal regularity, e.t.c. This paper is concerned with such estimates for semi-group generated by the Dirichlet Laplacian of fractional order in terms of the Besov spaces on an arbitrary open set of $mathbb R^d$.
