Conference Archive

Welcome to the archive of past GTA Philadelphia eventsĀ (previously the Graduate Student Conference in Geometry, Topology, and Algebra). Since its inception, this conference has provided a platform for graduate students in algebra, geometry, and topology to engage with cutting-edge research, present their own work, and connect with fellow researchers and faculty members.

Each year, we bring together a vibrant community of mathematicians to discuss new ideas, foster collaborations, and gain insights from distinguished keynote speakers. Most talks are delivered by graduate students, creating an enriching environment for peer-to-peer learning and academic growth.

Below, you will find links to previous conference editions, including schedules, abstracts, and speaker details. These archives serve as a valuable resource for revisiting past research discussions and tracking the evolution of topics in the field.
