Let be a commutative ring with unit. To every pair of -algebras and one can associate a simplicial set so that equals the set of polynomial homotopy classes of morphisms from to . We prove that is the set of homotopy classes of morphisms from to , where is the ind-algebra of polynomials on the -dimensional cube with coefficients in vanishing at the boundary of the cube. This is a generalization to arbitrary dimensions of a theorem of Cortiñas-Thom, which addresses the cases . As an application we give a simplified proof of a theorem of Garkusha that computes the homotopy groups of his matrix-unstable algebraic -theory space in terms of polynomial homotopy classes of morphisms.
