Abstract The paper deals with some control problems related to the Kolmogorov system for two interacting populations. For the first…

Abstract Let \(a<c<b)\) real numbers, \((\mathbb{B},|\cdot|)\) a (real or complex) Banach space, \(H\in C([a,b]\times [a,c]\times\mathbb{B},\mathbb{B})\), \(K\in C([a,b]^{2}\times\mathbb{B},\mathbb{B})\),  \(g\in C([a,b]),\mathbb{B} ,A:C([a,c],\mathbb{B})\rightarrow…

Abstract This paper deals with the light travel time effect in binary systems with variable components. The methods for estimation…

Abstract The paper deals with semilinear operator equations involving iterates of a strongly monotone symmetric linear operator. In particular there…

Abstract We establish compression-expansion type fixed point theorems for systems of operator inclusions with decomposable multivalued maps. The approach is…

Abstract The aim of this paper is to draw attention to a general principle for solving control problems for operator…

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