The generalized Vaserstein symbol
Lundi, 8 Avril, 2019 - 14:00
Résumé : 

In this talk, we begin with a brief discussion of the cancellation problem of projective modules. In particular, we will introduce the so-called Vaserstein symbol and explain how it was used by Fasel-Rao-Swan in the proof of the most recent result on stably free modules. Motivated by this, we explain our work on the generalization of the Vaserstein symbol and discuss some applications of the generalized Vaserstein symbol to the cancellation problem of projective modules.
