Numerical approach to the controllability of fractional order impulsive differential equations

open access: yesDemonstratio Mathematica, 2020
In this manuscript, a numerical approach for the stronger concept of exact controllability (total controllability) is provided. The proposed control problem is a nonlinear fractional differential equation of order α∈(1,2]\alpha \in (1,2] with non ...

A unified existence theory for evolution equations and systems under nonlocal conditions [PDF]

open access: yes, 2014
We investigate the effect of nonlocal conditions expressed by linear continuous mappings over the hypotheses which guarantee the existence of global mild solutions for functional-differential equations in a Banach space. A progressive transition from the

A class of abstract quasi-linear evolution equations of second order [PDF]

open access: yes, 1999
In this paper we study the abstract quasi-linear evolution equation of second order formula here in a general banach space z. it is well-known that the abstract quasi-linear theory due to kato [10, 11] is widely applicable to quasi-linear partial ...

Semilinear fractional differential equations: global solutions, critical nonlinearities and comparison results [PDF]

open access: yes, 2015
In this work we study several questions concerning to abstract fractional Cauchy problems of order α ∈ (0, 1). Concretely, we analyze the existence of local mild solutions for the problem, and its possible continuation to a maximal interval of existence.
