Research Article410.1007/s11075-024-01952-3Smooth connectivity in real algebraic varietiesOct 05, 2024Numerical AlgorithmsJoseph Cummings + 3 more +3Abstract A standard question in real algebraic geometry is to compute the number of connected components of a real algebraic variety in affine space. This manuscript provides algorithms for computing the number of connected components, the Euler characteristic, and deciding the connectivity between two points for a smooth manifold arising as the complement of a real hypersurface of a real algebraic variety. When considering the complement of the set of singular points of a real algebraic variety, this yields an approach for determining smooth connectivity in a real algebraic variety. The method is based upon gradient ascent/descent paths on the real algebraic variety inspired by a method proposed by Hong, Rohal, Safey El Din, and Schost for complements of real hypersurfaces. Several examples are included to demonstrate the approach.Read moreCiteListenSave
Research Article210.1007/s11075-024-01931-8A numerical algorithm for the computation of the noncentral beta distribution functionSep 10, 2024Numerical AlgorithmsVera Egorova + 3 more +3Abstract The noncentral beta distribution function is a generalization of the central beta distribution (the regularized incomplete beta function) that includes a noncentrality parameter. This paper describes an algorithm and provides a Matlab implementation for calculating the noncentral beta distribution function. Through a series of numerical tests, we demonstrate that the algorithm is accurate and efficient across a wide range of parameters.Read moreCiteListenSave
