Approximate solvability method for nonlocal impulsive evolution equation

Open Mathematics, 2023
In this article, without assuming the compactness of semigroup, we deal with the existence and uniqueness of a mild solution for semilinear impulsive evolution equation with nonlocal condition in a reflexive Banach space by applying the approximate ...

M-hypercyclicity of C0-semigroup and Svep of its generator

Concrete Operators, 2021
Let 𝒯 = (Tt)t≥0 be a C0-semigroup on a separable infinite dimensional Banach space X, with generator A. In this paper, we study the relationship between the single valued extension property of generator A, and the M-hypercyclicity of the C0-semigroup ...

Monoids, their boundaries, fractals and C*-algebras

Topological Algebra and its Applications, 2020
In this note we establish some connections between the theory of self-similar fractals in the sense of John E. Hutchinson (cf. [3]), and the theory of boundary quotients of C*-algebras associated to monoids.

Well-posedness of a boundary value problem for a class of third-order operator-differential equations

Boundary Value Problems, 2013
This paper investigates the well-posedness of a boundary value problem on the semiaxis for a class of third-order operator-differential equations whose principal part has multiple real characteristics.

A modification to the conformable fractional calculus with some applications

Alexandria Engineering Journal, 2020
In the conformable fractional calculus, TαTβ≠TβTα and IαIβ≠IβIα, where Tα and Iα are conformable fractional differential and integral operators, respectively. Also, Tβ≠Tnα and Iβ≠Inα, where β=nα for some n∈N.

Continuous spectrum of the 3D Euler equation is a solid annulus [PDF]

, 2010
In this note we give a description of the continuous spectrum of the linearized Euler equations in three dimensions. Namely, for all but countably many times $t\in \R$, the continuous spectrum of the evolution operator $G_t$ is given by a solid annulus ...

Lyapunov property of positive C_0-semigroups on non-commutative L^p spaces

Operators and Matrices, 2019
That the growth bound of a positive C0 -semigroup on classical Lp -space coincides with the spectral bound of its generator, is a well known result in classical semigroup theory.

A viscosity hybrid steepest-descent method for a system of equilibrium and fixed point problems for an infinite family of strictly pseudo-contractive mappings

Journal of Inequalities and Applications, 2012
Based on a viscosity hybrid steepest-descent method, in this paper, we introduce an iterative scheme for finding a common element of a system of equilibrium and fixed point problems of an infinite family of strictly pseudo-contractive mappings which ...
