Gaussian curvature of piecewise flat manifolds

Smooth surfaces are often approximated by triangulations. When the triangles are flat the curvature of the original surface becomes reflected in angle defects at vertices: the angles of the triangles meeting at a vertex do not sum to $2\pi$, and the difference is called the deficit angle. The deficit angle has been proposed as a measure of the gaussian curvature at vertices and I will give a rigorous interpretation and proof of this intuition.
(The talk will be in English.)
