A Class of Fractional Degenerate Evolution Equations with Delay [PDF]

open access: yesMathematics, 2020
We establish a class of degenerate fractional differential equations involving delay arguments in Banach spaces. The system endowed by a given background and the generalized Showalter–Sidorov conditions which are natural for degenerate type equations. We

Existence for Nonlinear Evolution Equations and Application to Degenerate Parabolic Equation [PDF]

open access: yesJournal of Applied Mathematics, 2014
We consider an abstract Cauchy problem for a doubly nonlinear evolution equation of the form d/dt𝒜u+ℬu∋ft in V′, t∈0, T, where V is a real reflexive Banach space, 𝒜 and ℬ are maximal monotone operators (possibly multivalued) from V to its dual V′.

Singularly perturbed hyperbolic problems on metric graphs: asymptotics of solutions

open access: yesOpen Mathematics, 2017
We are interested in the evolution phenomena on star-like networks composed of several branches which vary considerably in physical properties. The initial boundary value problem for singularly perturbed hyperbolic differential equation on a metric graph
