Parameter–Elliptic Fourier Multipliers Systems and Generation of Analytic and C Semigroups

open access: yesMathematics, 2022
We consider Fourier multiplier systems on Rn with components belonging to the standard Hörmander class S1,0mRn, but with limited regularity. Using a notion of parameter-ellipticity with respect to a subsector Λ⊂C (introduced by Denk, Saal, and Seiler) we

Real analyticity of Hausdorff dimension for expanding rational semigroups [PDF]

open access: yes, 2009
We consider the dynamics of expanding semigroups generated by finitely many rational maps on the Riemann sphere. We show that for an analytic family of such semigroups, the Bowen parameter function is real-analytic and plurisubharmonic.

Mild Solutions to the Cauchy Problem for Some Fractional Differential Equations with Delay

open access: yesAxioms, 2017
In this paper, we present new existence theorems of mild solutions to Cauchy problem for some fractional differential equations with delay. Our main tools to obtain our results are the theory of analytic semigroups and compact semigroups, the Kuratowski ...

Feller semigroups, Lp-sub-Markovian semigroups, and applications to pseudo-differential operators with negative definite symbols [PDF]

open access: yes, 2001
The question of extending L-p-sub-Markovian semigroups to the spaces L-q, q > P, and the interpolation of LP-sub-Markovian semigroups with Feller semigroups is investigated.

On the stochastic Allen–Cahn equation on networks with multiplicative noise

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
We consider a system of stochastic Allen–Cahn equations on a finite network represented by a finite graph. On each edge in the graph a multiplicative Gaussian noise driven stochastic Allen–Cahn equation is given with possibly different potential barrier ...

A characterization of the generators of analytic C0-semigroups in the class of scalar type spectral operators

open access: yesAbstract and Applied Analysis, 2004
In the class of scalar type spectral operators in a complex Banach space, a characterization of the generators of analytic C0-semigroups in terms of the analytic vectors of the operators is found.

On the global existence of mild solutions of nonlinear delay systems associated with continuous and analytic semigroups

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2008
In this paper we prove sufficient conditions for the existence of global solutions of nonlinear functional-differential evolution equations whose linear parts are infinitesimal generators of strongly continuous and analytic semigroups.

Dynamics of semigroups generated by analytic functions of the Laplacian on Homogeneous Trees

open access: yesComptes Rendus. Mathématique, 2023
Let $\Psi $ be a non-constant complex-valued analytic function defined on a connected, open set containing the $L^p$-spectrum of the Laplacian $\mathcal{L}$ on a homogeneous tree.

On continuity of solutions for parabolic control systems and input-to-state stability [PDF]

open access: yes, 2018
We study minimal conditions under which mild solutions of linear evolutionary control systems are continuous for arbitrary bounded input functions.
