Hilfer proportional nonlocal fractional integro-multipoint boundary value problems

open access: yesOpen Mathematics, 2023
In this article, we introduce and study a boundary value problem for (k,χ¯*)\left(k,{\bar{\chi }}_{* })-Hilfer generalized proportional fractional differential equation of order in an interval (1, 2], equipped with integro-multipoint nonlocal boundary ...

Minimal Nonnegative Solution of Nonlinear Impulsive Differential Equations on Infinite Interval

open access: yesBoundary Value Problems, 2011
The cone theory and monotone iterative technique are used to investigate the minimal nonnegative solution of nonlocal boundary value problems for second-order nonlinear impulsive differential equations on an infinite interval with an infinite number of ...

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 ...

Maximal regular boundary value problems in Banach-valued weighted space

open access: yesBoundary Value Problems, 2005
This study focuses on nonlocal boundary value problems for elliptic ordinary and partial differential-operator equations of arbitrary order, defined in Banach-valued function spaces. The region considered here has a varying bound and depends on a certain

Positive solutions of some nonlocal boundary value problems

open access: yesAbstract and Applied Analysis, 2003
We establish the existence of positive solutions of some m-point boundary value problems under weaker assumptions than previously employed. In particular, we do not require all the parameters occurring in the boundary conditions to be positive.

Boundary value problems with nonlocal conditions for hyperbolic systems of equations with two independent variables

open access: yesМатематичні Студії, 2020
Nonlocal boundary value problems for arbitrary order hyperbolic systems with one spatial variable are considered. A priori estimates for general nonlocal mixed problems for systems with smooth and piecewise smooth coefficients are obtained.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.
