Asymptotic stability of a perturbed abstract differential equations in Banach spaces [PDF]

open access: yesOperators and Matrices, 2020
Summary: This paper is mainly concerned with the asymptotic stability of the solutions of a perturbed abstract differential equation in Banach spaces. Let \(A\) be a generator of an exponentially stable operator semigroup and let \(C(t)\), \(t\geqslant 0\) be a linear bounded variable operator.

Embedding Operators in Vector-Valued Weighted Besov Spaces and Applications

open access: yesJournal of Function Spaces and Applications, 2012
The embedding theorems in weighted Besov-Lions type spaces 𝐵𝑙,𝑠𝑝,𝑞,𝛾 (Ω;𝐸0,𝐸) in which 𝐸0,𝐸 are two Banach spaces and 𝐸0⊂𝐸 are studied. The most regular class of interpolation space 𝐸𝛼 between 𝐸0 and E is found such that the mixed differential operator ...

A Class of Quasilinear Equations with Riemann–Liouville Derivatives and Bounded Operators

open access: yesAxioms, 2022
The existence and uniqueness of a local solution is proved for the incomplete Cauchy type problem to multi-term quasilinear fractional differential equations in Banach spaces with Riemann–Liouville derivatives and bounded operators at them.

Solvability and completeness of solutions of parabolic differential-operator equations [PDF]

open access: yesМатематичні Студії, 2011
We consider an abstract Cauchy problem for parabolic differential-operator equations in Hilbert spaces. Initial boundary value problems for parabolic equations are reduced to the Cauchy problem for a system of parabolic differential equations.

First-Order Regular and Degenerate Identification Differential Problems

open access: yesAbstract and Applied Analysis, 2015
We are concerned with both regular and degenerate first-order identification problems related to systems of differential equations of weakly parabolic type in Banach spaces. Several applications to partial differential equations and systems will be given

Extension of the Kantorovich Theorem to Equations in Vector Metric Spaces: Applications to Functional Differential Equations

open access: yes, 2023
The equation G(x,x)=y˜, where G:X×X→Y, and X,Y are vector metric spaces (meaning that the values of a distance between the points in these spaces belong to some cones E+,M+ of a Banach space E and a linear space M, respectively), is ...

On global regularity of 2D generalized magnetohydrodynamic equations [PDF]

open access: yes, 2013
In this article we study the global regularity of 2D generalized magnetohydrodynamic equations (2D GMHD), in which the dissipation terms are –ν(–Δ)αu and –κ(–Δ)βb. We show that smooth solutions are global in the following three cases: α≥1/2, β≥1; 0≤α≤1/2,

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 ...
