Novel results for two families of multivalued dominated mappings satisfying generalized nonlinear contractive inequalities and applications

open access: yesDemonstratio Mathematica
In this manuscript, we prove new extensions of Nashine, Wardowski, Feng-Liu, and Ćirić-type contractive inequalities using orbitally lower semi-continuous functions in an orbitally complete bb-metric space.

Existence of solutions and convergence analysis for a system of quasivariational inclusions in Banach spaces

open access: yesJournal of Inequalities and Applications, 2011
In order to unify some variational inequality problems, in this paper, a new system of generalized quasivariational inclusion (for short, (SGQVI)) is introduced.

Existence results for a class of hemivariational-like inequality problems

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this work, we establish existence results for a class of hemivariational-like inequality problems driven by a trifunction and perturbed by a bifunction.

Fixed point theory for multivalued φ-contractions

open access: yesFixed Point Theory and Applications, 2011
The purpose of this paper is to present a fixed point theory for multivalued φ-contractions using the following concepts: fixed points, strict fixed points, periodic points, strict periodic points, multivalued Picard and weakly Picard operators ...
