Boundary Terms for Massless Fermionic Fields [PDF]

open access: yes, 1995
Local supersymmetry leads to boundary conditions for fermionic fields in one-loop quantum cosmology involving the Euclidean normal to the boundary and a pair of independent spinor fields.

On a nabla fractional boundary value problem with general boundary conditions

open access: yesAIMS Mathematics, 2020
In this article, we consider a nabla fractional boundary value problem with general boundary conditions. Brackins & Peterson [5] gave an explicit expression for the corresponding Green’s function.

Light-Front Quantisation as an Initial-Boundary Value Problem

open access: yes, 1993
In the light front quantisation scheme initial conditions are usually provided on a single lightlike hyperplane. This, however, is insufficient to yield a unique solution of the field equations.

Dirichlet boundary value problem for Duffing's equation

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
We use direct variational method in order to investigate the dependence on parameter for the solution for a Duffing type equation with Dirichlet boundary value conditions.

Mixed algorithm for solving boundary value problem

open access: yesComputer Assisted Methods in Engineering and Science, 2023
Symbolic computation has been applied to Runge-Kutta technique in order to solve two-point boundary value problem. The unknown initial values are considered as symbolic variables, therefore they will appear in a system of algebraic equations, after the ...

Initial value problem for the free boundary magnetohydrodynamics with zero magnetic boundary condition

open access: yes, 2017
We show local existence and uniqueness of plasma(fluid)-vaccum free boundary problem of magnetohydrodynamic flow in three-dimensional space with infinite depth setting when magnetic field is zero on the free boundary.

On Bernoulli boundary value problem

open access: yesLe Matematiche, 2007
We give a constructive proof of the existence and uniqueness of the solution, under certain conditions, by Picard’s iteration. Moreover Newton’s iteration method is considered for the numerical computation of the solution.

Avery fixed point theorem applied to Hammerstein integral equations

open access: yesElectronic Journal of Differential Equations, 2019
We apply a recent Avery et al. fixed point theorem to the Hammerstein integral equation $$ x(t)=\int^{T_2}_{T_1}G(t,s)f(x(s))\,ds, \quad t\in[T_1,T_2].
