A fixed point result for semigroups of monotone operators and a solution of discontinuous nonlinear functional-differential equations

open access: yesHacettepe Journal of Mathematics and Statistics, 2021
We improve some fixed point theorems by stating a fixed point result for semigroups of monotone operators in the setting of ordered Banach spaces with a normal cone. We illustrate the usefulness of our results by proving the existence and conditional unicity of a solution of an initial value problem for discontinuous nonlinear functional-differential ...

The Lévy–Khintchine type operators with variable Lipschitz continuous coefficients generate linear or nonlinear Markov processes and semigroups [PDF]

open access: yesProbability Theory and Related Fields, 2010
Ito's construction of Markovian solutions to stochastic equations driven by a Lévy noise is extended to nonlinear distribution dependent integrands aiming at the effective construction of linear and nonlinear Markov semigroups and the corresponding processes with a given pseudo-differential generator.

A random walk for the solution sought: Remarks on the difference scheme approach to nonlinear semigroups and evolution operators

open access: yesSemigroup Forum, 1987
The author extends a previous result due to Crandall and Evans for the existence of a mild solution of the abstract Cauchy problem: \[ u'(t)+Au(t)\ni F(t,u(t)). \]
