Background: The understanding of the concept of function is complex for students of Basic Education to. The National Common Curriculum Base (BNCC) recommends that ideas of function, such as regularity, pattern generalisation and proportionality, be studie... see more

We study second order transmission problems across either a fractal surface or across the corresponding pre-fractal surface. Existence uniqueness and regularity results for the strict solution in both cases are proved.The asymptotic behaviour of the solut... see more

We study the Hölder continuity of the homogeneous gradient of the weak solutions of double obstacle problems involving nonlinear elliptic operators in the Heisenberg group.

The aim of this paper is to give a brief account on the problem of regularity forlinear elliptic PDEs of the second order.

We use the concept of approximation introduced by D.T Luc et al.  asgeneralized derivative for non-Lipschitz vector functions to consider vector problemswith non-Lipschitz data under inclusion constraints. Some calculus of approximationsare presented... see more

We study the Hölder continuity of the homogeneous gradient of the weak solutions of double obstacle problems involving nonlinear elliptic operators in the Heisenberg group.

In this note we review some recent results in [64, 95, 96] concerning necessary and sufficient conditions for the regularity of boundary points relatively to the Dirichlet problem for linear degenerate-parabolic operators with well-behaved fundamental sol... see more

In this talk some model examples of second order elliptic transmission problems with highly conductive layers will be described. Regularity and numerical results for solutions of transmission problems across fractal layers imbedded in Euclidean domains wi... see more
