    MSC 2010: 26A33, 34A37, 34K37, 34K40, 35R11This paper deals with the existence and uniqueness of solutions of two classes of partial impulsive hyperbolic differential equations with fixed time impulses and state-dependent delay involving the Caputo fractional derivative. Our results are obtained upon suitable fixed point theorems

    International audienceCloud computing is a state-of-the-art technological innovation providing an extensive list of benefits for almost every business and governmental, small or medium-sized organizations. It has truly revolutionized the computational era by cutting down cost and reducing complexities of infrastructural configurations for computational platforms. This state-of-the-art technology is rapidly being adapted by various large organizations from healthcare to critical infrastructure to carry out their business processes that, otherwise, would require large storage capacity, huge computational power, and expensive hardware. The purpose of this special issue was to arrange a venue for cloud researchers around the world to share their state-of-the-art research and development that could benefit the cloud community. This helped collect high-quality articles that reported recent research advances regarding security and privacy issues in cloud computing, covering various topics of interest

    In this work, we present some results on the existence of attractive solutions of fractional differential equations of the ψ-Hilfer hybrid type. The results on the existence of solutions are a consequence of the Schauder fixed point theorem. Next, we prove that all solutions are uniformly locally attractive

    Tyt. z nagłówka.Bibliogr. s. 220-222.In the present paper we investigate the existence of solutions for a system of integral inclusions of fractional order with multiple delay. Our results are obtained upon suitable fixed point theorems, namely the Bohnenblust-Karlin fixed point theorem for the convex case and the Covitz-Nadler for the nonconvex case.Dostępny również w formie drukowanej.KEYWORDS: integral inclusion, left-sided mixed Riemann-Liouville integral, time delay, solution, fixed point

    summary:This article deals with some results about the existence of solutions and bounded solutions and the attractivity for a class of fractional q{q}-difference equations. Some applications are made of Schauder fixed point theorem in Banach spaces and Darbo fixed point theorem in Fréchet spaces. We use some technics associated with the concept of measure of noncompactness and the diagonalization process. Some illustrative examples are given in the last section
