Regularity for minimizers for functionals of double phase with variable exponents

MA Ragusa, A Tachikawa - Advances in Nonlinear Analysis, 2019 - degruyter.com
The functionals of double phase type H (u):=∫| D u| p+ a (x)| D u| qdx,(q> p> 1, a (x)≥ 0) are
introduced in the epoch-making paper by Colombo-Mingione for constants p and q, and …

A new class of double phase variable exponent problems: Existence and uniqueness

Á Crespo-Blanco, L Gasiński, P Harjulehto… - Journal of Differential …, 2022 - Elsevier
In this paper we introduce a new class of quasilinear elliptic equations driven by the so-
called double phase operator with variable exponents. We prove certain properties of the …

Existence results for double phase implicit obstacle problems involving multivalued operators

S Zeng, Y Bai, L Gasiński, P Winkert - Calculus of Variations and Partial …, 2020 - Springer
In this paper we study implicit obstacle problems driven by a nonhomogenous differential
operator, called double phase operator, and a multivalued term which is described by …

Growth conditions and regularity for weak solutions to nonlinear elliptic pdes

P Marcellini - Journal of Mathematical Analysis and Applications, 2021 - Elsevier
We describe some aspects of the process/approach to interior regularity of weak solutions to
a class of nonlinear elliptic equations in divergence form, as well as of minimizers of …

Double phase implicit obstacle problems with convection and multivalued mixed boundary value conditions

S Zeng, VD Rădulescu, P Winkert - SIAM Journal on Mathematical Analysis, 2022 - SIAM
In this paper we consider a mixed boundary value problem with a nonhomogeneous,
nonlinear differential operator (called a double phase operator), a nonlinear convection term …

Double phase transonic flow problems with variable growth: nonlinear patterns and stationary waves

A Bahrouni, VD Rădulescu, DD Repovš - Nonlinearity, 2019 - iopscience.iop.org
In this paper we are concerned with a class of double phase energy functionals arising in
the theory of transonic flows. Their main feature is that the associated Euler equation is …

[图书][B] Partial differential equations in anisotropic Musielak-Orlicz spaces

Anisotropic and inhomogeneous spaces, which are at the core of the present study, may
appear exotic at first. However, the reader should abandon this impression once they realize …

[PDF][PDF] Isotropic and anisotropic double-phase problems: old and new

VD Radulescu - Opuscula Mathematica, 2019 - yadda.icm.edu.pl
We are concerned with the study of two classes of nonlinear problems driven by differential
operators with unbalanced growth, which generalize the (p, q)-and (p (x), q (x))-Laplace …

Constant sign solutions for double phase problems with superlinear nonlinearity

L Gasiński, P Winkert - Nonlinear Analysis, 2020 - Elsevier
We study parametric double phase problems involving superlinear nonlinearities with a
growth that need not necessarily be polynomial. Based on truncation and comparison …
