Computability of Homology for Compact Absolute Neighbourhood Retracts
In this note we discuss the information needed to compute the homology groups of a topological space. We argue that the natural class of spaces to consider are the compact absolut...

Shortest paths on 3-D simple Lie groups with nonholonomic constraint
— In this paper we study the Carnot-Caratheodory metrics on SU(2) S3 , SO(3) and SL(2) induced by their Cartan decomposition and by the Killing form. Besides computing explicitly...
