Analyticity of semigroups generated by operators with generalized Wentzell boundary conditions
Klaus‐Jochen Engel, Genni Fragnelli · Advances in Differential Equations · 2005
In this note we introduce a general framework which allows us to prove in a unified and systematic way that operators with Wentzell-type boundary conditions generate analytic semigroups on function spaces with bounded trace operator. The abstract generation result is illustrated in three concrete examples.
