,A Strong Variant of Weyl’s Theorem Under Functional Calculus and Perturbations,The aim of this paper is the study of a new and strong variant (.) of the classical Weyl’s theorem, for operators defined on Banach spaces, under functional calculus. Furthermore, we give some results on the permanence of (.) theorem under commuting perturbations, as algebraic or finite-dimensional commuting perturbations.

A Degenerate Operator in Non Divergence Form,In this paper we consider a fourth order operator in non divergence form . := ., where . is a function that degenerates somewhere in the interval. We prove that the operator generates an analytic semigroup, under suitable assumptions on the function .. We extend these results to a general operator . := ..

On Oscillatory Behavior of Third Order Half-Linear Difference Equations,This paper deals with the oscillatory behavior of third order half-linear difference equations. We present new oscillation criteria, which improve, extend and simplify existing ones in the literature. The results are illustrated by some examples.
