Solution sets of differential equations in abstract spaces

, 1996
Aim of the monograph is to analyze the structure of the solution set of a differential equations in the more general case of abstract topological (infinite dimensional) spaces. Specifically, we consider both the spaces with a paucity of useful properties,

A novel hybrid framework for efficient higher order ODE solvers using neural networks and block methods

Scientific Reports
In this paper, the author introduces the Neural-ODE Hybrid Block Method, which serves as a direct solution for solving higher-order ODEs. Many single and multi-step methods employed in numerical approximations lose their stability when applied in the ...

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

International Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

dynoGP: Deep Gaussian Processes for Dynamic System Identification

International Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.

On the Order of Singularity of the Generalized Solution of the Volterra Integral Equation of Convolutional Type in Banach Spaces

Известия Иркутского государственного университета: Серия "Математика", 2014
In the study of Volterra integral equations of convolution type defined on the semi-axis with the Fredholm operator in the main part and the operator-valued kernel K = K(t) in Banach spaces we ordinarily solved the problem of constructing a generalized K(

Several inequalities concerning real interpolation in the weighted Lebesgue and Morrey spaces and related bilinear estimates

Journal of Inequalities and Applications
In this paper, we establish several interpolation inequalities in the weighted Lebesgue spaces and Morrey spaces. By using the classical Calderón–Zygmund decomposition with respect to ω (a weight function), we prove that L p ( ω ) ∩ BMO ( R n ) ⊂ L q ( ω
