Regularity for nonlinear elliptic equations and systems

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2020
We study the regularity of weak solutions to the elliptic system in divergence form divA(x, Du)=0 in an open set Ω of R^n, n≥2. The vector field A(x.ξ), A: Ω×R^(m×n)→R^(m×n), has a variational nature in the sense that A(x,ξ)= Dξ f(x,ξ), where f:Ω×R^(m×n)→

Quadrature error functional expansions for the simplex when the integrand function has singularities at vertices [PDF]

open access: yesMathematics of Computation, 1980
In a previous paper by Lyness, an asymptotic expansion for the quadrature error functional for the n-dimensional simplex, valid when the integrand is an analytic function, was given. In this paper we develop the analogue of this result to cover the cases in which the integrand function has singularities of a specified nature at one or more vertices of ...

Integrals with two-variable generating function in the integrand

open access: yesMontes Taurus journal of pure and applied mathematics, 2021
The main motive of this study is to present a new class of generalized integral formulae which involve a generating function of two variables G(u, x). By this approach we deduce a set of new outcomes, which are integrals associated with generalized hypergeometric function, Laguerre, Hermite and Bessel polynomials, Kampe de Feriet hypergeometric series ...

On the best possible description of an exceptional set in asymptotic estimates for Laplace–Stieltjes integrals [PDF]

open access: yesМатематичні Студії, 2011
For the Laplace–Stieltjes integrals new description of the exceptional set in asymptotic upper estimates in terms of the maximum of the integrand function is obtained.

A relaxation result in BV for integral functionals with discontinuous integrands [PDF]

open access: yesESAIM: Control, Optimisation and Calculus of Variations, 2007
Summary: We prove a relaxation theorem in BV for a non coercive functional with linear growth. No continuity of the integrand with respect to the spatial variable is assumed.

A goodness‐of‐fit test for regression models with discrete outcomes

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Regression models are often used to analyze discrete outcomes, but classical goodness‐of‐fit tests such as those based on the deviance or Pearson's statistic can be misleading or have little power in this context. To address this issue, we propose a new test, inspired by the work of Czado et al.

Donaldson-Witten theory and indefinite theta functions

open access: yesJournal of High Energy Physics, 2017
We consider partition functions with insertions of surface operators of topologically twisted N=2 $$ \mathcal{N}=2 $$, SU(2) supersymmetric Yang-Mills theory, or Donaldson-Witten theory for short, on a four-manifold.
