Positive solutions for second-order differential equations of Kirchhoff type on the half-line

4 years ago

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

4 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…
