Piecewise convex interpolation
Abstract Let \(n\in N\) and the following two systems of \(n+1\) real values: \[ 0=x_{0}<x_{1}<\ldots<x_{n}=1 \] \[ 0=y_{0},\ y_{1},\ \ldots,\…

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…
On the Controllability of a System Modeling Cell Dynamics Related to Leukemia
AbstractIn this paper, two control problems for a symmetric model of cell dynamics related to leukemia are considered. The first…
