WebThis course offers an introduction to discrete and computational geometry. Emphasis is placed on teaching methods in combinatorial geometry. Many results presented are recent, and include open (as yet unsolved) problems. Course Info Instructor Dr. Csaba Toth Departments Mathematics Topics Engineering Computer Science Algorithms and Data … Suppose (S, V) is a closed connected marked surface and d is a PL metric on (S, V). Then for any function K^{*}: V\rightarrow (-\infty , 2\pi ) with \sum _{v\in V}K^{*}(v)=2\pi \chi (S), there exists a PL metric d', unique up to scaling and isometry homotopic to the identity on (S, V), such that d' is discrete … See more Two PL metrics d, d' on (S, V) are discrete conformal if there exist sequences of PL metrics d_{1}=d, \ldots , d_{m}=d' on (S, V) and triangulations {\mathcal {T}}_{1}, \ldots , {\mathcal {T}}_{m} … See more For any k \in {\mathbb {R}}, \mathbf{F }(v + k(1, 1, \ldots , 1)) = \mathbf{F }(v).
