摘要：The convex geometry in Euclidean space is based on the Minkowski summation of two sets. It originated from H. Brunn’s thesis in 1887 and H. Minkowski’s paper in 1903. In this talk, we introduce a summation for two sets in hyperbolic space, and we call it the hyperbolic summation. We develop a hyperbolic convex geometry by use of our hyperbolic summation. This is joint work with Dr Botong Xu.
