Japanese Mahjong Japanese Mahjong Japanese Mahjong (Japanese: 麻雀, 麻将 or マージャン; "mājan"), also known as Rīchi Mahjong, is a variation of mahjong. While the basic rules to the game are retained, the variation features a unique set of rules such as "rīchi" and the use of "dora". The main mahjong article contains general terms, but only English and Japanese terms are used here. Terms like "chow," "pung," and "kong" are not used in this variation, yet their functions are still used. Instead, they are referred to in Japanese as "chī", "pon", and "kan". In 1924, a soldier named Saburo Hirayama brought the
Chow variety Hilbert scheme is a variant of the Chow varieties. There is always a map (called the cycle map) from the Hilbert scheme to the Chow variety. A Chow quotient parametrizes closures of generic orbits. It is constructed as a closed subvariety of a Chow variety. Kapranov's theorem says that the moduli space formula_3 of stable genus-zero curves with "n" marked points is the Chow quotient of Grassmannian formula_4 by the standard maximal torus. Chow variety In mathematics, and more particularly in the field of algebraic geometry, Chow coordinates are a generalization of Plücker coordinates, applying to "m"-dimensional algebraic varieties of
