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 ...

Stability result of the Lamé system with a delay term in the internal fractional feedback
Acta Universitatis Sapientiae: Mathematica, 2021 In this article, we consider a Lamé system with a delay term in the internal fractional feedback. We show the existence and uniqueness of solutions by means of the semigroup theory under a certain condition between the weight of the delay term in the ...

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.

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 ...

The Dixmier problem, lamplighters and Burnside groups [PDF]
, 2009 J. Dixmier asked in 1950 whether every non-amenable group admits uniformly bounded representations that cannot be unitarised. We provide such representations upon passing to extensions by abelian groups.

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.

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 ...
