  • An involution on bicubic maps and beta(0,1)-trees 

    Claesson, Anders; Kitaev, Sergey; Mier Vinué, Anna de (2015)
    Article
    Accés obert
    Bicubic maps are in bijection with (0 ; 1)-trees. We introduce two new ways of decomposing (0 ; 1)-trees. Using this we de ne an endofunc- tion on (0 ; 1)-trees, and thus also on bicubic maps. We show that ...
