Flach system on quaternionic Hilbert-Blumenthal surfaces and distinguished periods

Abstract  In this talk, we will report some integrality result on the ratio of the quaternionic distinguished period associated to a Hilbert modular form and the quaternionic Petersson norm

Homotopy of manifolds through a cubic method

Abstract In several occasions, I have talked about some recent progresses on the unstable homotopy of manifolds made by Stephen Theriault and myself. But no details of the proof were presented. In
