Shepard operator of least squares thin-plate spline type
AbstractWe obtain some new Shepard type operators based on the classical, the modified Shepard methods and the least squares thin…
Analysis of the effectiveness of the treatment of solid tumors in two cases of drug administration
AbstractA complete stability analysis of the equilibrium solutions of a system modeling tumor chemotherapy is performed in two cases of…
Positive solutions for second-order differential equations of Kirchhoff type on the half-line
AbstractThe aim of the present paper is to study the existence of nontrivial nonnegative solutions for asecond-order boundary value problem…
A unified variational approach to discontinuous differential equations
AbstractA direct variational technique involving Clarke generalized gradient is used to treat general boundary value problems with discontinuous nonlinearities. Based…
Fixed point–critical point hybrid theorems and application to systems with partial variational structure

Study on Integrodifferential Evolution Systems with Nonlocal Initial Conditions
AbstractThe work is concerned with systems of abstract integrodifferential equations with general nonlocal initial conditions. To allow the nonlinear terms…
Space-time upscaling of reactive transport in porous media
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
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
AbstractThis paper deals with aa perturbed heavy ball system with vanishing damping that contains a Tikhonov regularization term, in connection…
