Amitsur Algebra Seminar ***************************** Time: Thursday, Nov. 3, 12:00 ~V 13:15 Place: room 209, Mathematics building Speaker: Eliyahu Rips (HUJI) Title: THE CANONICAL FORM OF ELEMENTS IN GENERALIZED SMALL CANCELLATION GROUPS Abstract: The generalized small cancellation theory was developed in the works of Novikov, Adian, Ol'shanski, Ivanov, Ossin, Gromov, Delzant, the present speaker and others. It gives means to construct finitely generated groups with exotic properties. When applying the generalized small cancellation theory, one of the biggest difficulties is the actual verification that a given group has a presentation that satisfies the generalized small cancellation conditions. The canonical form of elements provides an alternative approach to this difficulty. When applicable, it reduces the so called contiguity diagrams to direct contact between the relations.
