Ping Pong Patches

Future Work

Spring 2022
Undergraduate researchers: Jordan Grant, Jeremy Krill, Samuel Perales
Mentor: Teddy Weisman
Faculty advisor: Jeff Danciger

This semester, the Ping Pong Group finished its work from the previous two semesters of TXGL. We finalized an algorithm which worked with a generalized version of the Ping Pong Lemma to find intervals of RP1RP1 meeting certain containment conditions which guarantee the faithfulness of a particular group representation in SL(2,R)SL(2,R). To showcase our work, we create a new visualization tool in the GitHub repository along with a web-based demo of a few valid intervals we found for a cyclic free product, triangle group, and surface group.
