Fejes Toth Lecture Series at U of C

Laszlo Fejes Toth (1915-2005) was a Hungarian mathematician specialized in geometry who is widely regarded as one of the founding fathers of the field Discrete Geometry that lies on the border line of mathematics and computer science. Karoly Bezdek started the Fejes Toth lecture series in 2009 honoring the legacy of Laszlo Fejes Toth. Every semester CCDG hosts a distinguished Fejes Toth speaker. For more details on the invited speakers and their talks see the website at http://ccdg.math.ucalgary.ca/.

Center for Computational and Discrete Geometry (CCDG)

The Center for Computational and Discrete Geometry (CCDG) was established at the Dept. of Math. and Stats. of the Univ. of Calgary in 2003. The major goals of CCDG are to maintain an active research program in the broad area of combinatorial, computational, convex, and discrete geometry including both theoretical research and applications of the theory to sciences and engineering. In addition, CCDG hosts visitors, special seminars, and lecture series (such as the Fejes Toth Lecture Series) to support the training of graduate students and to accomodate joint research work. Faculty researchers associated with CCDG include K. Bezdek, T. Bisztriczky, M. Cavers, T. Dihn, F. Fodor, C. Laflamme, J. Ling, M. Pouzet, B. Sands, N. Sauer, K. Seyffarth, and Y. Zinchenko.
