Semidefinite lifts of polytopes

Coauthors: Richard Z. Robinson, Rekha R. Thomas


Recently, there has been a renewed interest in understanding the
existence of small linear or semidefinite representations for
polytopes. These representations, which are obtained by adding extra variables, are deeply connected to certain special factorizations of the slack matrix of the polytopes.
In this talk, we explore this connection to present some results on the size of semidefinite lifts of polytopes, with focus on examples, surveying what is known in the area.
