Bourgain, Brezis and Mironescu theorem for fractional Sobolev spaces with variable exponents
Annali di Matematica Pura ed Applicata, 2022A Bourgain–Brezis–Mironescu-type theorem for fractional Sobolev spaces with variable exponents is established for sufficiently regular functions. We prove, however, that a limiting embedding theorem for these spaces fails to hold in general.

Constant sign solutions for double phase problems with variable exponents
Applied Mathematics Letters, 2022. 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 perturbation with a growth that need not necessarily be polynomial ...

Gradient Estimates of ω-Minimizers to Double Phase Variational Problems with Variable Exponents
, 2021We are concerned with an optimal regularity for ω-minimizers to double phase variational problems with variable exponents where the associated energy density is allowed to be discontinuous. We identify basic structure assumptions on the density for the

Boundedness of fractional maximal operators for double phase functionals with variable exponents
Journal of Mathematical Analysis and Applications, 2021In this paper, we study the boundedness of variable fractional maximal operators M τ ( ⋅ ) for double phase functionals Φ p ( ⋅ ) , q ( ⋅ ) ( x , t ) = t p ( x ) + ( b ( x ) t ) q ( x ) , where τ ( ⋅ ) is a measurable function on R N satisfying 0 ≤ inf x

Timoshenko beams with variable‐exponent nonlinearity
Mathematical Methods in the Applied Sciences, 2023In this paper, we consider the following Timoshenko system with a nonlinear feedback having a variable exponent and a time‐dependent coefficient . We establish, for the first time as per our knowledge, explicit energy decay rates for this system depending on both and .

Extrapolation to weighted Morrey spaces with variable exponents and applications
Proceedings of the Edinburgh Mathematical Society, 2021This paper establishes the mapping properties of pseudo-differential operators and the Fourier integral operators on the weighted Morrey spaces with variable exponents and the weighted Triebel–Lizorkin–Morrey spaces with variable exponents.

Mathematical methods in the applied sciences
In this article, we focussed on a nonlinear viscoelastic Kirchhoff‐type equation with distributed delay and variable‐exponents. The blow‐up solutions of the problem are proved under suitable hypothesis, and by using an integral inequality due to Komornik,
