Kazuaki Taira, Angelo Favini, Silvia Romanelli · Studia Mathematica · 2001
This paper is devoted to the functional analytic approach to the problem of construction of Feller semigroups with Wentzell boundary conditions in the characteristic case. Our results may be stated as follows: We can construct Feller semigroups cor
