Positive solutions of a boundary value problem with integral boundary conditions [PDF]

open access: yes, 2011
We consider boundary-value problems studied in a recent paper. We show that some existing theory developed by Webb and Infante applies to this problem and we use the known theory to show how to find improved estimates on parameters μ*, λ so ...

Direct localized boundary-domain integro-differential formulations for physically nonlinear elasticity of inhomogeneous body [PDF]

open access: yes, 2005
A static mixed boundary value problem (BVP) of physically nonlinear elasticity for a continuously inhomogeneous body is considered. Using the two-operator Green-Betti formula and the fundamental solution of an auxiliary linear operator, a non-standard ...

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

open access: yes, 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 ...

Positive solutions of nonlinear fourth-order boundary-value problems with local and non-local boundary conditions [PDF]

open access: yes, 2008
We establish new existence results for multiple positive solutions of fourth-order nonlinear equations which model deflections of an elastic beam. We consider the widely studied boundary conditions corresponding to clamped and hinged ends and many non ...

Positive solutions of boundary value problems with nonlinear nonlocal boundary conditions [PDF]

open access: yesOpuscula Mathematica, 2016
We consider the existence of at least three positive solutions of a nonlinear first order problem with a nonlinear nonlocal boundary condition given by \[\begin{aligned} x^{\prime}(t)& = r(t)x(t) + \sum_{i=1}^{m} f_i(t,x(t)), \quad t \in [0,1 ...

Boundary oscillations and nonlinear boundary conditions

open access: yesComptes Rendus. Mathématique, 2006
We study how oscillations in the boundary of a domain affect the behavior of solutions of elliptic equations with nonlinear boundary conditions of the type ∂ u

Doubly Nonlinear Parabolic Equation with Nonlinear Boundary Conditions

open access: yesJournal of Mathematical Analysis and Applications, 2001
A necessary and sufficient condition for global existence of all positive classical solutions is given. The proof relies on the construction of suitable upper and lower solutions.

A free boundary problem for the p-Laplacian with nonlinear boundary conditions

open access: yesAnnali di Matematica Pura ed Applicata (1923 -), 2023
AbstractWe study a nonlinear generalization of a free boundary problem that arises in the context of thermal insulation. We consider two open sets $$\Omega \subseteq A$$ Ω ⊆ A , and we search for an optimal A in order to minimize a ...
