On MAP Estimates and Source Conditions for Drift Identification in SDEs

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT We consider the inverse problem of identifying the drift in an stochastic differential equation (SDE) from n$n$ observations of its solution at M+1$M+1$ distinct time points. We derive a corresponding maximum a posteriori (MAP) estimate, we prove differentiability properties as well as a so‐called tangential cone condition for the forward ...

Existence theorems for nonlinear differential equations having trichotomy in Banach spaces [PDF]

open access: yes, 2017
summary:We give existence theorems for weak and strong solutions with trichotomy of the nonlinear differential equation $$ \dot {x}(t)=\mathcal {L}( t)x(t)+f(t,x(t)),\quad t\in \mathbb {R}\leqno {\rm (P)} $$ where $\{\mathcal {L}(t)\colon t\in \mathbb ...

Hausdorff and fractal dimensions of attractors for functional differential equations in Banach spaces

open access: yes, 2023
The main objective of this paper is to obtain estimations of Hausdorff dimension as well as fractal dimension of global attractors and pullback attractors for both autonomous and nonautonomous functional differential equations (FDEs) in Banach spaces ...

On Cahn–Hilliard Type Viscoelastoplastic Two‐Phase Flows

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT This contribution deals with a model for viscoelastoplastic two‐phase flows of Cahn–Hilliard type. We present the modeling framework for the flow, the notion of a generalized solution, namely the so‐called dissipative solution, and the key ideas of the existence proof.

On Semilinear Integro-Differential Equations with Nonlocal Conditions in Banach Spaces

open access: yesAbstract and Applied Analysis, 2012
We study the abstract Cauchy problem for a class of integrodifferential equations in a Banach space with nonlinear perturbations and nonlocal conditions. By using MNC estimates, the existence and continuous dependence results are proved.

Existence and asymptotic stability of periodic solutions for impulsive delay evolution equations

open access: yesAdvances in Difference Equations, 2019
This paper we devote to considering the periodic problem for the impulsive evolution equations with delay in Banach space. By using operator semigroup theory and the fixed point theorem, we establish some new existence theorems of periodic mild solutions
