A covering approach to eigenvalue bounds for the fractional p-Laplacian

Demonstratio Mathematica
We study Weyl-type lower bounds for the variational eigenvalues associated with a weighted fractional p-Laplacian on bounded domains with Lipschitz boundary in a critical (limit) case.

Penalty method for unilateral contact problem with Coulomb's friction in time-fractional derivatives

Demonstratio Mathematica
The purpose of this work is to study a mathematical model that describes a contact between a deformable body and a rigid foundation. A linear viscoelastic Kelvin-Voigt constitutive law with time-fractional derivatives describes the material’s behavior ...
