SkanderH Posted February 20, 2006 Posted February 20, 2006 Help please! Two associative functions on the the unit square: [0,1]^2 -->[0,1] x,y --> T(x,y) and S(x,y) What is the ordinal sum of these two functions on [0,1]^2 ? I know it is not T(x,y)+S(x,y) Does ordinal some have something to do with ordinal numbers? Thanks
