On nonobtuse simplicial partitions

In this talk we surveys some results on acute and  nonobtuse simplices and associated spatial partitions. These  partitions are relevant in numerical mathematics, including piecewise polynomial approximation theory and the finite element method. Special attention is paid to a basic type of non-obtuse simplices called path-simplices, the generalization of right triangles to higher dimensions. In addition to applications in numerical mathematics,  we give examples of the appearance of acute and non-obtuse simplices in other areas of mathematics.
