DESCRIPTION:In geometric group theory\, one of the central que
stions is to understand what algebraic properties
are invariant under quasi-isometries. In this dire
ction\, in recent years there has been a lot of wo
rk on proving results in rigidity for non-positive
ly curved spaces. In this talk we will study a fam
ily of higher graph manifolds and some of its prop
erties that are invariant under quasi-isometries.
We will show that isomorphisms between fundamental
groups of higher graph manifolds preserve the dec
omposition into pieces. In addition\, for the subf
amily of those manifolds called cusp-decomponsable
manifolds\, we will also show that the inclusion
of walls and pieces induces quasi-isometric embedd
ings.\n\n
