DESCRIPTION:Title: Combination of groups with hyperbolically embedded subgr
 oups and groups with well-defined relative dehn functions.\n\nAbstract: Hy
 perbolically embedded subgroups were defined by F. Dahmani\, V. Guirardel 
 and D. Osin as a generalization of peripheral structure of relatively hype
 rbolic groups. We revisit the definition of these subgroups using the Bowd
 itch graph approach which was described by E. Martinez Pedroza and F. Rash
 id. Then we prove a combination theorem for hyperbolically embedded subgro
 ups where each edge group of the splitting graph of groups is conjugate in
 to a 'subgroup' of a peripheral structure of the adjacent vertex group. Mo
 reover\, after defining groups with well-defined relative dehn function\, 
 we provide a similar combination theorem for these groups which follows fr
 om constructing a Cayley_Abel graph in the first part of this talk. The me
 thod of proof provides lower and upper bounds of the relative Dehn functio
 ns in terms of the relative Dehn functions of the vertex groups. This is a
  joint work with E. Martinez Pedroza.\n
