Hardy Type Inequalities Related to Degenerate Elliptic Differential Operators
Lorenzo D'Ambrosio
We prove some Hardy type inequalities related to quasilinear second order degenerate elliptic differential operators L_p(u):=-\nabla_L^*(\abs{\nabla_L u}^{p-2}\nabla_L u). If ϕis a…

Some Remarks on a General Construction af Approximation Processes
Lorenzo D'Ambrosio, Elisabetta Mangino
The aim of this paper is to study the characteristics of a general method to produce a new approximation sequence from a given one, by using suitable convex combinations.

Approximation of *weak-to-norm continuous mappings
Lorenzo D'Ambrosio
The purpose of this paper is to study the approximation of vector valued mappings defined on a subset of a normed space. We investigate Korovkin-type conditions under which a given…
