Query: A^1-homotopy theory and contractible varieties: a survey   We survey some topics in ${\mathbb A}^1$-homotopy theory. Our main goal is to
highlight the interplay between ${\mathbb A}^1$-homotopy theory and affine
algebraic geometry, focusing on the varieties that are "contractible" from
various standpoints.
