Analytic auxiliary mass flow to compute master integrals in singular kinematics
Journal of High Energy PhysicsThe computation of master integrals from their differential equations requires boundary values to be supplied by an independent method. These boundary values are often desired at singular kinematical points.

MathematicsIn this paper, a multi-patch weakly singular isogeometric boundary element method (WSIGABEM) for two-dimensional elastostatics is proposed. Since the method is based on the weakly singular boundary integral equation, quadrature techniques, dedicated to ...

The solution to Wheeler-DeWitt is eight
, 1994 We describe a new geometrical solution to the Wheeler-DeWitt equation in two dimensional quantum gravity. The solution is the amplitude of a surface whose boundary consists of two tangent loops.

On quasilinear parabolic evolution equations in weighted Lp-spaces II [PDF]
, 2013 Our study of abstract quasi-linear parabolic problems in time-weighted L_p-spaces, begun in [17], is extended in this paper to include singular lower order terms, while keeping low initial regularity.

Electronic Journal of Differential Equations, 2016 This article concerns singular boundary-value problems for a vacuum diode model. We prove the integrability of a system of nonlinear differential equations and construct a complete system of the first integrals; thus developing a method for solving ...

A higher-order method for nonlinear singular two-point boundary value problems
International Journal of Mathematics and Mathematical Sciences, 2002 We present a finite difference method for a general class of nonlinear singular two-point boundary value problems. The order of convergence of the method for such a general class of problems is higher than the previous reported methods. The method yields

A local target specific quadrature by expansion method for evaluation of layer potentials in 3D
, 2018 Accurate evaluation of layer potentials is crucial when boundary integral equation methods are used to solve partial differential equations. Quadrature by expansion (QBX) is a recently introduced method that can offer high accuracy for singular and ...

Ain Shams Engineering Journal, 2018 In this paper, a mixed finite difference method is proposed to solve singularly perturbed differential difference equations with mixed shifts, solutions of which exhibit boundary layer behaviour at the left end of the interval using domain decomposition.

Scaling limits of random normal matrix processes at singular boundary points [PDF]
, 2019 We give a method for taking microscopic limits of normal matrix ensembles. We apply this method to study the behaviour near certain types of singular points on the boundary of the droplet.
