Linear eigenvalues and a nonlinear boundary value problem [PDF]

Pacific Journal of Mathematics, 1970
Abstract : A nonlinear boundary value problem for elliptic partial differential equations is considered. The principal result generalizes a previous result on a two point boundary value problem for a nonlinear second order ordinary differential equation.

Nonlocal Boundary Value Problem for Nonlinear Impulsive qk-Integrodifference Equation

Abstract and Applied Analysis, 2014
A nonlinear impulsive integrodifference equation within the frame of qk-quantum calculus is investigated by applying using fixed point theorems. The conditions for existence and uniqueness of solutions are obtained.

Nonlinear boundary value problem for nonlinear second order differential equations with impulses

Electronic Journal of Qualitative Theory of Differential Equations, 2005
The paper deals with the impulsive nonlinear boundary value problem \[ u''(t) = f(t,u(t),u'(t)) \quad\mbox{for a.e.}\ t \in [0,T], \] \[ u(t_j+) = J_j(u(t_j)),\quad u'(t_j+) = M_j(u'(t_j)),\quad j = 1,\ldots,m, \] \[ g_1(u(0),u(T)) = 0, \quad g_2(u'(0),u'

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.

A singular nonlinear boundary value problem with Neumann conditions [PDF]

Opuscula Mathematica, 2005
We study the existence of solutions for the equations \(x^{\prime\prime}\pm g(t,x)=h(t)\), \(t\in (0,1)\) with Neumann boundary conditions, where \(g:[0,1] \times (0,+\infty) \to [0,+\infty)\) and \(h:[0,1] \to \mathbb{R}\) are continuous and \(g(t,\cdot)

The existence of solutions for nonlinear fractional boundary value problem and its Lyapunov-type inequality involving conformable variable-order derivative

Journal of Inequalities and Applications, 2020
We consider a nonlinear fractional boundary value problem involving conformable variable-order derivative with Dirichlet conditions. We prove the existence of solutions to the considered problem by using the upper and lower solutions’ method with ...

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 ...

Multiderivative methods for nonlinear second order boundary value problems [PDF]

, 1985
Second, fourth and sixth order methods are developed and analysed for the numerical solution of non-linear second order boundary value problems. The methods arise from a two-step recurrence relation involving exponential terms, these being replaced by ...

On solvability of nonlinear boundary value problems with integral condition for the system of hyperbolic equations

Electronic Journal of Qualitative Theory of Differential Equations, 2015
For system of hyperbolic equations of second order a nonlinear boundary value problem with integral condition is considered. By introducing new unknown functions the investigated problem is reduced to an equivalent problem involving one-parametered ...

The Yamabe Problem and Nonlinear Boundary Value Problems

Journal of Differential Equations, 1995
The paper is concerned with the scalar curvature equation with prescribed mean curvature on the boundary of a given Riemannian manifold. Just as in \textit{T. Ouyang} [Trans. Am. Math. Soc. 331, No. 2, 503-527 (1992; Zbl 0759.35021)], this Riemannian manifold is assumed to have negative constant scalar curvature in the interior and zero mean curvature ...
