Hölder regularity for logarithmic double phase problems

Ky Ho, Yun-Ho Kim, Patrick Winkert

We investigate boundedness and regularity properties of weak solutions to a class of generalized logarithmic double phase equations with variable exponents. The considered operator…

Mixed double phase equations with local and nonlocal operators

Anupma Arora, Shilpa Gupta, Patrick Winkert

In this paper, we study a new class of mixed double phase problems that combine local and nonlocal operators. We consider two different models. The first model is driven by the fra…

Degenerate singular Kirchhoff problems in Musielak-Orlicz spaces

Umberto Guarnotta, Patrick Winkert

In this paper we study quasilinear elliptic Kirchhoff equations driven by a non-homogeneous operator with unbalanced growth and right-hand sides that consist of sub-linear, possibl…

On singularly perturbed -Laplace Schrödinger equation with logarithmic nonlinearity

Deepak Kumar Mahanta, Tuhina Mukherjee, Patrick Winkert

This article focuses on the study of the existence, multiplicity and concentration behavior of ground states as well as the qualitative aspects of positive solutions for a

Critical double phase problems involving sandwich-type nonlinearities

Csaba Farkas, Alessio Fiscella, Ky Ho +1

In this paper we study problems with critical and sandwich-type growth represented by \begin{align*} -\operatorname{div}\Big(|\nabla u|^{p-2}\nabla u + a(x)|\nabla u|^{q-2}\nabla u…

Logarithmic double phase problems with generalized critical growth

Rakesh Arora, Ángel Crespo-Blanco, Patrick Winkert

In this paper we study logarithmic double phase problems with variable exponents involving nonlinearities that have generalized critical growth. We first prove new continuous and c…
