A method of Analytic Centers for Quadratically Constrained Convex Quadratic Programs

SIAM Journal on Numerical Analysis, 1991
The authors consider maximizing a concave quadratic function under convex quadratic constraints: an interior point method is developed. Complexity results are provided.

Quadratic convergence for cell-centered grids

Applied Numerical Mathematics, 1988
Rectangular cell-centered finite difference approximations of a plane pressure-flow equation in a rectangular region with no-flow conditions at the boundary are considered. Despite a formal inconsistency in the finite difference equations, due to the use of cell-centered rather than point- distributed grids, it is shown that the solution errors are \(O(

The period function of reversible Lotka-Volterra quadratic centers

Journal of Differential Equations, 2022
In this paper, the authors prove that the period function of reversible Lotka-Volterra quadratic systems is monotone, unless the associated center is isochronous, by using a criterion coming from [\textit{F. Mañosas} and \textit{J. Villadelprat}, J. Differ. Equations 246, No. 6, 2415--2433 (2009; Zbl 1171.34022)].
