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 ...

Global solutions for 3D nonlocal Gross-Pitaevskii equations with rough data
Electronic Journal of Differential Equations, 2012 We study the Cauchy problem for the Gross-Pitaevskii equation with a nonlocal interaction potential of Hartree type in three space dimensions. If the potential is even and positive definite or a positive function and its Fourier transform decays ...

Approximation by Translates of a Positive Definite Function
Journal of Mathematical Analysis and Applications, 1996 The purpose of the paper is to investigate density properties of translates of a single function. Denote by \(\mathcal P\) the set of all positive definite functions on \(\mathbb{R}^n\) such that \(\sum^m_{i,j=1} c_ic_j f(x_i-x_j)\geq 0\) whenever \(x_1,\dots,x_m\in\mathbb{R}^n\) and \(c_1,\dots,c_m\in\mathbb{R}\). Let \(\Omega\) be a compact subset of

Advanced Materials, EarlyView.Heterostructure photodiode devices of p‐type WSe2 with n‐type NiPS3 constructs spectrally protected spin‐polarized photocurrents. The energy of the excitation photon serves as an independent control parameter for spin‐selective photocurrent generation. ABSTRACT Efficient generation and control of spin‐polarized currents in semiconductors remain central

3D‐Printed Corneal Substitutes: Materials, Fabrication, and Preclinical Progress
Advanced Materials Technologies, EarlyView.Successful clinical translation of 3D‐printed corneal substitutes relies on the interplay between the bioink properties, cellular component, and the fabrication process. These factors influence the critical properties of the construct, including optical transparency, mechanical stability, suture retention, that ultimately govern long‐term stromal ...

Metric spaces and positive definite functions [PDF]
Transactions of the American Mathematical Society, 1938 As poo we get the space Em with the distance function maxi-, ... I xi X. Let, furthermore, lP stand for the space of real sequences with the series of pth powers of the absolute values convergent. Similarly let LP denote the space of real measurable functions in the interval (0, 1) which are summable to the pth power, while C shall mean the space of ...
