In this 24-minute episode of Living Proof podcast, join Dan Aspel and Marianne Freiberger as they interview mathematicians Tomer Schlank (Hebrew University of Jerusalem) and Jeremy Hahn (MIT) about their groundbreaking work. Discover how Schlank and Hahn, along with collaborators Robert Burklund and Ishan Levy, disproved Ravenel's telescope conjecture—a significant announcement made during the June 2023 INI workshop "A panorama of homotopy theory." Learn about the implications of this mathematical breakthrough and its profound impact on the field of homotopy theory. The episode was recorded on July 7, 2023, and connects to the 2018 INI programme and its 2023 follow-on workshop at the Isaac Newton Institute for Mathematical Sciences.
