A note on a beam equation with nonlinear boundary conditions.
If -A is the generator of an equibounded -semigroup and 0 < Re α < m (m integer), its fractional power can be described in terms of the semigroup, through a formula that is only valid if a certain function is nonzero. This paper is devoted to the study of the zeros of .
In this paper we study the behaviour of maximal monotone multivalued highly oscillatory operators. We construct Reuss-Voigt-Wiener and Hashin-Shtrikmann type bounds for the minimal sections of G-limits of multivalued operators by using variational convergence and convex analysis.
