Nonsymmetric solutions of a nonlinear boundary value problem [PDF]
The paper is concerned with nonlinear second-order ordinary differential equation subject to symmetric nonlinear boundary conditions \[ \begin{aligned} u''(x)&=a| u(x)| ^{p-1}u(x),\,\,\,x\in (-l,l),\\ u'(\pm l)&=\pm | u(\pm l)| ^{q-1}u(\pm l),\end{aligned} \leqno (1) \] where \(a,\,l>0\). Using the shooting method, the author investigates the existence

dynoGP: Deep Gaussian Processes for Dynamic System Identification
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.

Boundary value problems for hypergenic function vectors
This article mainly studies the boundary value problems for hypergenic function vectors in Clifford analysis. Firstly, some properties of hypergenic quasi-Cauchy type integrals are discussed. Then, by the Schauder fixed point theorem the existence of the

Nonlinear boundary value problems and operators TT∗
AbstractWe consider nonlinear boundary value problems of the type Lƒ + Nƒ = 0 for the existence of solutions. It is assumed that L is a 2nth-order linear differential operator in the real Hilbert space S = L2[a, b] which admits a decomposition of the form L = TT∗ where T is an nth-order linear differential operator and N is a nonlinear operator defined

The Galerkin-Implicit Methods for Solving Nonlinear Hyperbolic Boundary Value Problem
This paper is concerned with finding the approximation solution (APPS) of a certain type of nonlinear hyperbolic boundary value problem (NOLHYBVP). The given BVP is written in its discrete (DI) weak form (WEF), and is proved that it has a unique APPS,

A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

On a boundary value problem for nonlinear functional differential equations
We consider the problem u′(t)=H(u)(t)+Q(u)(t), u(a)=h(u), where H,Q:C([a,b];R)→L([a,b];R) are, in general, nonlinear continuous operators, H∈ℋabαβ(g0,g1,p0,p1), and h:C([a,b];R)→R is a continuous functional.

A singular nonlinear boundary-value problem
In this paper we prove an existence and uniqueness theorem for the singular nonlinear boundary-value problem $$displaylines{ (|y'(t)|^py'(t))'+frac{phi}{y^{lambda}(t)}=0 hbox{ in } (0,1),cr y(0)=0=y(1), }$$ where $pgeq 0$, $lambda$ is a positive constant,
