Binary Multi-Triangulations: Issues and Developments Luiz Velho IMPA - Instituto de Matematica Pura e Aplicada Binary multi-triangulations (BMT), provide an effective mechanism for multiresolution simplicial decomposition of n-dimensional manifolds. In this talk, I will discuss the main ideas related to BMTs, including their basic properties, requirements and operations with them. I will also show how the generic BMT concept can be implemented in 2 and 3 dimensions.
