Discrete Differential Geometry and Applications
May 17-21, 2010
Discrete differential geometry is concerned with: (1) discretization of concepts from classical differential and conformal geometry of surfaces; (2) creation of fast, flexible algorithms for computations with the objects of this discrete theory; and (3) application of the theory and software in mathematics, science, and engineering. The conference will be organized around these 5 interconnected themes.
