Stationary Kirchhoff equations and systems with reaction terms

4 years ago

AbstractIn this paper, the operator approach based on the fixed point principles of Banach and Schaefer is used to establish…

Componentwise localization of critical points for functionals defined on product spaces

4 years ago

AbstractA new notion of linking is introduced to treat minima as minimax points in a unitary way. Critical points are…

Krasnoselskii type theorems in product Banach spaces and applications to systems of nonlinear transport equations and mixed fractional differential equations

AbstractThe aim of the present paper is to study the existence of nontrivial nonnegative solutions for asecond-order boundary value problem…

Space-time upscaling of reactive transport in porous media

5 years ago

AbstractReactive transport in saturated/unsaturated porous media is numerically upscaled to the spacetime scale of a hypothetical measurement through coarse grained…

On the Durrmeyer-type variant and generalizations of Lototsky–Bernstein operators

5 years ago

Abstract The starting points of the paper are the classic Lototsky–Bernstein operators. We present an integral Durrmeyer-type extension and investigate…

Tikhonov regularization of a perturbed heavy ball system with vanishing damping

5 years ago

AbstractThis paper deals with aa perturbed heavy ball system with vanishing damping that contains a Tikhonov regularization term, in connection…

Global Random Walk Solutions for Flow and Transport in Porous Media
