Morel's conjecture on rational points in the -homotopy category
Morel's conjecture on rational points in the -homotopy category
Let be the base field, let be a smooth variety over , and write
for the MorelVoevodsky homotopy category of schemes over $F$. The set $X(F)$ consists of the $F$-rational points of $X$, and $(,X)$ denotes the morphisms fromto in this category. Define an equivalence relation on generated by elementary -homotopies, namely by pairs for which there exists a morphism with and . Morel's conjecture. If is a smooth variety, the natural map
is surjective and identifies the right-hand side with the quotient of by the equivalence relation generated by
This conjecture describes morphisms from the point to the -homotopy category in terms of rational points modulo -homotopy. The supplied text gives no resolution status, so it remains open here.
