On the behavior of a capillary surface in a wedge
Paul Concus,Robert Finn +1 more
TL;DR: A limiting case among corresponding properties that hold for surfaces defined over domains with smooth boundaries is described, as well as a formal extension to n-dimensional surfaces; here the interest centers on the fact that it is the mean curvature of an (n-1)-dimensional boundary element that controls the local behavior of the n- dimensional solution surface.

A generalized conjugate gradient method for the numerical solution of elliptic partial differential equations
Paul Concus,Gene H. Golub,Dianne P. O'Leary +2 more
- 01 Jan 1976
TL;DR: A generalized conjugate gradient method for solving sparse, symmetric, positive-definite systems of linear equations, principally those arising from the discretization of boundary value problems for elliptic partial differential equations is considered.
A generalized conjugate gradient method for nonsymmetric systems of linear equations
Paul Concus,Gene H. Golub +1 more
TL;DR: A generalized conjugate gradient method for solving systems of linear equations having nonsymmetric coefficient matrices with positive-definite symmetric part based on splitting the matrix into its symmetric and skew-symmetric parts, which simplifies in this case, as only one of the two usual parameters is required.
Static menisci in a vertical right circular cylinder
TL;DR: In this paper, the solution of the differential equation describing the equilibrium meniscus in a vertical right circular cylinder is obtained over the entire range of contact angles and Bond numbers (dimensionless ratios of gravitational to capillary forces).
Numerical solution of a nonlinear hyperbolic equation by the random choice method
TL;DR: In this paper, the numerical solution of a nonlinear hyperbolic equation not fulfilling the strict nonlinearity condition is considered, and a solution procedure is developed based on the random choice method, which permits the sharp tracking of discontinuities.
