Remarks on the Generation of Semigroups of Nonlinear Operators on p-Fréchet Spaces, 0 < p < 1

Cubo, 2011
In this paper we study the convergence properties of the Crandall-Liggett sequence , for A a nonlinear operator on some important non-locally convex F-spaces (called p-Fréchet spaces with 0 < p < 1) and the generation of the corresponding strongly ...

Existence results for nondensely defined semilinear functional differential inclusions in Fréchet spaces

Electronic Journal of Qualitative Theory of Differential Equations, 2005
In this paper, a recent Frigon nonlinear alternative for contractive multivalued maps in Fréchet spaces, combined with semigroup theory, is used to investigate the existence of integral solutions for first order semilinear functional differential ...

On Semigroup Presentations and Efficiency

, 2002
The purpose of this paper is twofold. First we determine some forms of the relations in a finite semigroup presentation with zero deficiency which does or does not define a group. Moreover, we conclude that a finite Rees matrix semigroup Script M sign[G;

Existence of solutions in the alpha-norm for partial functional differential equations with infinite delay

Electronic Journal of Qualitative Theory of Differential Equations, 2012
In this work, we prove a result on the local existence of mild solution in the $\alpha$-norm for some partial functional differential equations with infinite delay. We suppose that the linear part generates a compact analytic semigroup.

On quasi-contractivity of C 0-semigroups on Banach spaces [PDF]

, 2004
A basic result in semigroup theory states that every C-0-semigroup is quasi-contractive with respect to some appropriately chosen equivalent norm. This paper contains a counterpart of this well-known fact.

Dynamics of Stochastic Coral Reefs Model with Multiplicative Nonlinear Noise

Discrete Dynamics in Nature and Society, 2016
Little seems to be known about the ergodicity of random dynamical systems with multiplicative nonlinear noise. This paper is devoted to discern asymptotic behavior dynamics through the stochastic coral reefs model with multiplicative nonlinear noise.

Global attractors for a nonlinear viscoelastic equations with strong damping velocity-dependent material density

Boundary Value Problems
In this paper, we study the long-time behavior of the semigroup  S ( t ) $S(t)$  generated by a nonlinear viscoelastic equation with strong damping in a bounded domain Ω of  R N $\mathbb{R}^{N}$ .

Periodic trajectories for evolution equations in Banach spaces

Electronic Journal of Differential Equations, 2005
The existence of periodic solutions for the evolution equation $$ y'(t)+Ay(t) i F(t,y(t)) $$ is investigated under considerably simple assumptions on $A$ and $F$.
