Calculating TC for homotopy fixed points of the Adams summand

Abstract

This talk will disprove the telescope conjecture at height 2 and primes p > 5, by a direct computational approach. Specifically, the speaker will prove that, for k sufficiently large and Z acting by the Adams operation Ψp+1, V (2)∗ TC(l
hpkZ) has non-finite homotopy groups.
