A complete asymptotic expansion for the semi-exponential Post-Widder operators
Abstract In the present paper, we study the asymptotic properties of the semi-exponential Post-Widder operator. It is connected with \(p(x)=x^{2}\).…

Fixed Point Results and the Ekeland Variational Principle in Vector B-Metric Spaces
Abstract In this paper, we extend the concept of b-metric spaces to the vectorial case, where the distance is vector…
On equilibrium in control problems with applications to evolution systems
Abstract In this paper we examine a mutual control problem for systems of two abstract evolution equations subject to a…
Optimal finite element approximation of unique continuation
Abstract We consider finite element approximations of ill-posed elliptic problems with conditional stability. The notion of {\emph{optimal error estimates}} is…
Computational orders of convergence of iterative methods for Richards’ equation
