SUMMARY:Graduate student seminar - Noam Zimhoni and Michael Chapman
DESCRIPTION:*First talk:*16-17\n*Noam Zimhoni*: Some trees and some forests of some triangles.\n*Abstract:* In 1934 B. Berggren first discovered the surprising result that \nevery Pythagorean triangle is the result of the product of the vector $(3, 4, \n5)$ given as a column vector by word in three matrices, and that every \ntriangle is obtained in this manner exactly once and in primitive form. We \nwill discuss a proof of this theorem given by Katayama S. and some \ngeneralization of it including original work.\n*Second talk:* 17-18\n*Michael Chapman: *Almost Solutions\n*Abstract:* When does an approximate solution to a problem close to an actual \nsolution to the original problem? Which problems, if they have an instance \nthat is almost solvable, then there is a complete solution for this instance? \nIn this talk I will introducea rigorous study of these kinds of questions, \nboth from a theoretical computer science viewpoint (Property Testing) as well \nas from a group theoretical perspective (Group Stability).\nThis talk will b...
