Analytic Feller Semigroups Via Hypergeometric Series

, 2014
Degenerate differential operators with Wentzell boundary conditions are proved to generate analytic semigroups in the space of continuous functions on [0,1] using hypergeometric series.

Sinclair Homomorphisms and Semigroups of Analytic Functions

Journal of Functional Analysis, 1997
The author studies homomorphisms from the convolution algebra \(L^1(\mathbb{R}^+)\) into certain Banach algebras of functions on the closed unit disc \(\mathbb{D}\). It is shown that for the algebra \(A^+\) of absolutely convergent Taylor series on \(\mathbb{D}\), every homomorphism \(\Phi\) is of the form \(\Phi(h)= \int^\infty_0 h(t)\nu^t dt ...

Dirichlet forms for general Wentzell boundary conditions, analytic semigroups, and cosine operator functions

Electronic Journal of Differential Equations, 2006
The aim of this paper is to study uniformly elliptic operators with general Wentzell boundary conditions in suitable $L^p$-spaces by using the approach of sesquilinear forms.

Analytic semigroups generated by square Hörmander operators

, 1996
Summary: We show that degenerate elliptic operators of Hörmander type realized in \(\mathbb{R}^n\) generate analytic semigroups in proper Sobolev spaces and we characterize some real interpolation spaces related to the original problem.
