SUMMARY:Cubical quotients of cubical nonproducts - Kasia Jankiewicz (Unive
 rsity of California\, Santa Cruz)

DESCRIPTION:Burger-Mozes constructed examples of simple groups acting geom
 etrically on a CAT(0) complex\, which is a product of trees. As a counterp
 oint\, we prove that every group acting geometrically on a CAT(0) cube com
 plex which is not a product\, admits a nontrivial quotient which also admi
 ts a geometric action on a CAT(0) cube complex. Our construction relies on
  the cubical version of small cancelation theory. This is joint work with 
 M. Arenas and D. Wise.\n&nbsp\;\n
