On the Gromov Norm


Speaker: Lewis Bowen, UC DAVIS
Location: 693 Kerr
Start time: Wed, May 26 2004, 4:10PM

This talk will be an elementary introduction to the Gromov norm (for the uninitiated). We will also present some new results: measure homology and simplicial homology are isometric with respect to the l^1-norm. The Gromov norm of the product of 2 surfaces can be computed from asymptotic estimates of "polytopal Gromov norm" of the product of 2 n-gons. We give new upper and lower bounds on this norm.
