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 …

The objective of the paper is to investigate a dynamical system called a differential
variational-hemivariational inequality (DVHVI) which couples an abstract variational …

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 …

This paper is devoted to the study of the L∞-bound of solutions to the double-phase
nonlinear problem with variable exponent by the case of a combined effect of concave …

In this paper we study quasilinear elliptic equations driven by the so-called double phase
operator and with a nonlinear boundary condition. Due to the lack of regularity, we prove the …

We consider a double phase Dirichlet problem with both convex and nonconvex unilateral
constraints (variational-hemivariational inequality). Using variational techniques and tools …

We consider a nonautonomous (p, q)-equation with unbalanced growth and a reaction
which exhibits the combined effects of a parametric “concave"((p-1)-sublinear) term and of a …

In this paper, we study multiplicity results for double phase problems of Kirchhoff type with
right-hand sides that include a parametric singular term and a nonlinear term of subcritical …

In this paper we study quasilinear elliptic equations driven by the variable exponent double
phase operator and a right-hand side that contains a parametric term and a superlinear …

In this paper, we study a class of singular double phase problems defined on Minkowski
spaces in terms of Finsler manifolds and with right-hand sides that allow a certain type of …
