Abstract: Morel’s A1-degree is the analogue of the Brouwer degree in A1-homotopy theory.
It is the key input in A1-enumerative geometry, that is enumerative geometry over an arbitrary field where answers are valued in the Grothendieck-Witt ring of the field.
In the talk I will give a brief introduction to the A1-degree and its applications and present formulas to compute it including a formula using the multivariate Bézoutian. This is based on joint work with Thomas Brazelton and Stephen McKean.
