If you have a question about this talk, please contact Andrew Thomason.

I will discuss the problem of cutting the (discrete or continuous) d-dimensional torus economically, so that no nontrivial cycle remains. This improves, simplifies and/or unifies results of Bollobas, Kindler, Leader and O’Donnell, of Raz and of Kindler, O’Donnell, Rao and Wigderson. More formal, detailed abstract(s) appear in http://www.math.tau.ac.il/_{nogaa/PDFS/torus3.pdf and in http://www.math.tau.ac.il/}nogaa/PDFS/torusone.pdf.

Joint work with Bo’az Klartag.
