DESCRIPTION:The least common ancestor (LCA) mapping is an important tool t
 o reconcile discordance between gene tree and species tree\, and has been 
 well studied in the literature.\nIn this talk\, we report some recent resu
 lts in studying general reconciliations\, i.e.\, leaf-preserving and order
 -preserving maps\, between gene tree and species tree. Here we introduce t
 hree cost models to infer\, respectively\, the gene duplication\, gene los
 s and deep coalescent events. And we also show that the canonical partial 
 order dened on the set of reconciliations is compatible with these cost m
 odels. Finally\, we discuss how to generalize these results to non-binary 
 gene trees.\n
