In this paper we are concerned with second order elliptic equations in unbounded domains O of R^2 . We establish existence and uniqueness theorems under the assumptions that the leading coefficients are bounded and measurable in O and satisfy a suitable c... see more

Given a Borel function having convex effective domain, but not necessarily bounded or with nonempty interior, locally bounded in the relative interior of its effective domain and verifying an upper semicontinuity type assumption in its effective domain, w... see more

Sharp estimates for the resolvent of a linear elliptic second-order partial differential operator under Dirichlet homogeneous boundary conditions are derived via a symmetrization technique.

We introduce a new type of integral, which solves the problem of finding antiderivatives but which does not contain the improper integral.

In this paper we propose some conjectures and problems, in different fields of analysis, presenting also their motivations.

A class of nondivergence unifrmly elliptic equations with measurable coefficients is studied. The oscillation of the coefficients near a Lebesgue point is assumed to be controlled by increasing functions satisfying Dini's condition.Under this assumption, ... see more
