Existence of solutions for a class of multivalued functional integral equations of Volterra type via the measure of nonequicontinuity on the Fréchet space
Radosław Pietkun
The existence of continuous not necessarily bounded solutions of nonlinear functional Volterra integral inclusions in infinite dimensional setting is shown with the aid of the meas…
Solvability of inclusions of Hammerstein type
Radosław Pietkun
A fairly general continuation theorem of Leray-Schauder type for the class of so-called admissible multimaps is set forth. This result is then used to establish a universal rule fo…
Structure of the solution set to Volterra integral inclusions and applications
Radosław Pietkun
The topological and geometric structure of the solution set to Volterra integral inclusions in Banach spaces is investigated. It is shown that the set of solutions in the sense of…
Guiding potential method for differential inclusions with nonlocal conditions
Radosław Pietkun
The existence of solutions of some nonlocal initial value problems for differential inclusions is established. The guiding potential method is used and the topological degree theor…
Acyclicity of the solution set of two-point boundary value problems for second order multivalued differential equations
Radosław Pietkun
The topological and geometrical structure of the set of solutions of two-point boundary value problems for second order differential inclusions in Banach spaces is investigated. It…
On the properties of the solution set map to Volterra integral inclusion
Radosław Pietkun
For the multivalued Volterra integral equation defined in a Banach space, the set of solutions is proved to be , without auxiliary conditions imposed in Theorem 6 [J. Math. An…
