The Union of Colorful Simplices Spanned by a Colored Point Set
A simplex spanned by a colored point set in Euclidean d-space is colorful if all vertices have distinct colors. The union of all full-dimensional colorful simplices spanned by a c...

Calculations on Critical Points under Gaussian Blurring
Abstract. The behaviour of critical points of Gaussian scale-space images is mainly described by their creation and annihilation. In existing literature these events are determined...

An Improved Coordinate System for Point Correspondences of 2D Articulated Shapes
To find corresponding points in different poses of the same articulated shape, a non rigid coordinate system is used. Each pixel of each shape is identified by a pair of distinct c...

A Point Process Describing the Component Sizes in the Critical Window of the Random Graph Evolution
We study a point process describing the asymptotic behavior of sizes of the largest components of the random graph G(n, p) in the critical window, that is, for p = n−1 + λn−4/...

Uzawa type algorithms for nonsymmetric saddle point problems
In this paper, we consider iterative algorithms of Uzawa type for solving linear nonsymmetric saddle point problems. Specifically, we consider systems, written as usual in block fo...
