The Functional Integral for a Free Particle on a Half-Plane
, 1992 A free non-relativistic particle moving in two dimensions on a half-plane can be described by self-adjoint Hamiltonians characterized by boundary conditions imposed on the systems.

On the Coherent State Path Integral for Linear Systems [PDF]
, 2005 We present a computation of the coherent state path integral for a generic linear system using ``functional methods'' (as opposed to discrete time approaches).

Path-Integral Quantum Monte Carlo simulation with Open-Boundary Conditions
, 2017 The tunneling decay event of a metastable state in a fully connected quantum spin model can be simulated efficiently by path integral quantum Monte Carlo (QMC) [Isakov $et~al.$, Phys. Rev. Lett. ${\bf 117}$, 180402 (2016).].

Analytic structure of radiation boundary kernels for blackhole perturbations
, 2005 Exact outer boundary conditions for gravitational perturbations of the Schwarzschild metric feature integral convolution between a time-domain boundary kernel and each radiative mode of the perturbation. For both axial (Regge-Wheeler) and polar (Zerilli)

Electronic Journal of Qualitative Theory of Differential Equations, 2016 We discuss boundary value problems for Riemann-Liouville fractional differential equations with certain fractional integral boundary conditions. Such boundary conditions are different from the widely considered pointwise conditions in the sense that they

Exact and Fast Numerical Algorithms for the Stochastic Wave Equation [PDF]
, 2003 On the basis of integral representations we propose fast numerical methods to solve the Cauchy problem for the stochastic wave equation without boundaries and with the Dirichlet boundary conditions.

Dynamical boundary conditions for integrable lattices [PDF]
Journal of Physics A: Mathematical and General, 1998 Some special solutions to the reflection equation are considered. These boundary matrices are defined on the common quantum space with the other operators in the chain. The relations with the Drinfeld twist are discussed.

Advances in Difference Equations, 2019 We establish the existence of positive solutions to a class of a singular nonlinear Hadamard-type fractional differential equations with infinite-point boundary conditions (BCs) or integral BCs.
