Naive vs. genuine A¹-connectedness
Sawant, Anand
Original · EN
We show that the triviality of sections of the sheaf of A¹-chain connected components of a space over finitely generated separable field extensions of the base field is not sufficient to ensure the triviality of the sheaf of its A¹-chain connected components, contrary to the situation with genuine A¹-connected components. As a consequence, we show that there exists an A¹-connected scheme for which the Morel-Voevodsky singular construction is not A¹-local.
