New Caputo fractional differential equation of higher order on unbounded interval and solvability in the Hölder space C 0 , q ( Ω ) $C^{0,q}(\Omega )$

Journal of Inequalities and Applications
We define a new Caputo fractional differential equation of higher-order on unbounded interval { D α c w ( t ) = f ( t ) , 0 ≤ t < ∞ , w ( 0 ) = w ′ ( 0 ) = w ( 4 ) ( 0 ) = w ( 5 ) ( 0 ) = ⋯ = w ( n ) ( 0 ) = 0 , w ‴ ( 0 ) = ∫ 0 η ( η − s ) α − 1 Γ ( α ...

RAKOTCH TYPE EXTENSION OF DARBO’S FIXED POINT THEOREM AND AN APPLICATION

In this paper, we present a new extension of Darbo’s fixed point theorem inspired by Rakotch’s contraction. We also provide the alternative version of Leray-Schauder type of our new result.

Some generalizations of Darbo's fixed point theorem under weak topology features with application to a Volterra-type integral equation

Applied General Topology
In this paper, we provide some generalizations of Darbo's fixed point theorem for larger classes of contraction. Our results are investigated under the weak topology of a Banach space using the measure of weak noncompactness. The results presented in the

Coalitional Equilibria of Strategic Games [PDF]

Let N be a set of players, C the set of permissible coalitions and G an N-playerstrategic game. A profile is a coalitional-equilibrium if no coalition permissible coalition in C has a unilateral deviation that profits to all its members.
