A family of singular differential equations are investigated and
theorems on the solvability of a number of initial problems for the considered family
The Sylvester problem and uniqueness sets in classes of entire functions uniqueness set. Within the framework of this general problem, we establish
uniqueness theorems in various
Bounded Solutions of Semi-Linear Parabolic Differential Equations with Unbounded Delay Terms differential equation in a Banach space with unbounded positive operators is studied. The main
theorem Generalized functional differential equations: Existence and uniqueness of solutions into the underlying system. The main result of the paper provides a general existence and
uniqueness theorem Stability and Non-Uniqueness of Equilibrium in an Open Market Model by their price elasticities. We obtained the conditions on the stability and non-
uniqueness of equilibrium
Kantorovich's Fixed Point Theorem in Metric Spaces and Coincidence PointsExistence and
uniqueness theorems are obtained for a fixed point of a mapping of a complete metric
On the Existence of Grötzsch–Wiener PointsAbstract: We consider the simplest class of countably connected domains with the
