Abstract: The object of this paper is the tameness conjecture introduced in [B], which describes an arbitrary graded $k$-algebra homomorphism of polytopal rings. We will give further evidence of this conjecture by showing supporting results concerning joins, multiples and products of polytopes. [B] Bruns, W.; Gubeladze, J.: \emph{Polytopal Linear Algebra}. Beitr. Algebra Geom. \textbf{43} (2002), 479--500.

Keywords: Polytopal ring, graded k-algebra homomorphism, tame homomorphism

Classification (MSC2000): 13F99, 14M25
