## Abstract Given a graph __G__, for each Ο β__V__(__G__) let __L__(Ο ) be a list assignment to __G__. The wellβknown choice number __c__(__G__) is the least integer __j__ such that if |__L__(Ο )| β₯__j__ for all Ο β__V__(__G__), then __G__ has a proper vertex colouring Ο with Ο(Ο ) β __L__ (Ο ) (βΟ β__
## Abstract A __rooted graph__ is a pair (__G, x__) where __G__ is a simple undirected graph and __x__ Ο΅ __V__(__G__). If __G__ if rooted at __x__, then its __rotation number h(G, x)__ is teh minimum number of edges in a graph __F__, of the same order as __G__, such that for all __v__ Ο΅ __V(F)__ we
