Cardinality of Multivariate Polynomial Ring #

The main result in this file is mv_polynomial.cardinal_mk_le_max, which says that the cardinality of mv_polynomial σ R is bounded above by the maximum of #R, and ℵ₀.

The cardinality of the multivariate polynomial ring, mv_polynomial σ R is at most the maximum of #R, and ℵ₀
