Abstract:

Structure preserving discretizations in geometry and mathematical physics - Discrete conformal mappings and their generalizations: circle patterns, discrete conformal equivalence, hyperbolic structures, ring patterns. Applications to differential geometry of surfaces (discrete minimal and constant mean curvature surfaces), computer graphics (texture mappings) and integrable models of mathematical physics. Partially based on modern research with presentation of open problems.
