Petar Pavešić (9/1/21): Category weight estimates of minimal triangulations

When one applies computational methods to study a specific manifold or a polyhedron it is often convenient to have as small triangulation of it as possible. However there are certain limitations on the size of a triangulation, depending on the complexity of the space under scrutiny. The de

The general rational laws of trigonometry | WildTrig: Intro to Rational Trigonometry

We establish the laws of rational trigonometry in the very general planar setting of having a general bilinear form which determines the notions of quadrance and spread. Pleasantly the laws of RT are still the familiar ones, but the interest is in seeing just how elegantly and simply these
