Speaker: Gaohong Wang (Western)
Title: "Fiber sequences and the Hopf fibration"
Room: MC 107

Abstract: We introduce fiber sequences and the Hopf fibration S3S2 in HoTT, and we show that the Hopf fibration induces equivalences between the homotopy groups πk of S3 and S2 for k>2. We also deduce that π2(S2) is equivalent to Z. We will review the background on truncations and connectedness in this talk too.
