Parametrization for non-linear problems with integral boundary conditions
Electronic Journal of Qualitative Theory of Differential Equations, 2012 We consider the integral boundary-value problem for a certain class of non-linear system of ordinary differential equations of the form \begin{equation*} \frac{dx\left(t\right)}{dt} =f\left(t,x\left(t\right)\right), t\in \left[0,T\right],\: x\in \mathbb ...

BRST Invariant Boundary Conditions for Gauge Theories [PDF]
, 1996 A systematic way of generating sets of local boundary conditions on the gauge fields in a path integral is presented. These boundary conditions are suitable for one--loop effective action calculations on manifolds with boundary and for quantum cosmology.

Analysis of Two-Dimensional Heat Transfer Problem Using the Boundary Integral Equation
Advances in Mathematical Physics, 2022 In this paper, we examine the problem of two-dimensional heat equations with certain initial and boundary conditions being considered. In a two-dimensional heat transport problem, the boundary integral equation technique was applied.

No-Boundary Proposal as a Path Integral with Robin Boundary Conditions [PDF]
Physical Review Letters, 2019 Realising the no-boundary proposal of Hartle and Hawking as a consistent gravitational path integral has been a long-standing puzzle. In particular, it was demonstrated by Feldbrugge et al. that the sum over all universes starting from zero size results in an unstable saddle point geometry.

Electronic Journal of Qualitative Theory of Differential Equations, 2010 The quasilinearization method coupled with the method of upper and lower solutions is used for a class of nonlinear boundary value problems with integral boundary conditions. We obtain some less restrictive sufficient conditions under which corresponding

Boundary Conditions as Dynamical Fields
, 2015 The possibility of treating boundary conditions in terms of a bilocal dynamical field is formalized in terms of a boundary action. This allows for a simple path-integral perturbation theory approach to physical effects such as radiation from a time ...

On the Volterra property of a boundary problem with integral gluing condition for mixed parabolic-hyperbolic equation [PDF]
, 2013 In the present work we consider a boundary value problem with gluing conditions of integral form for parabolic-hyperbolic type equation. We prove that the considered problem has the Volterra property.

Path integrals and boundary conditions
, 2006 The path integral approach to quantum mechanics provides a method of quantization of dynamical systems directly from the Lagrange formalism. In field theory the method presents some advantages over Hamiltonian quantization. The Lagrange formalism preserves relativistic covariance which makes the Feynman method very convenient to achieve the ...
