Description |
Abstract: I will provide an elementary definition of the cobordism ring of involutions of smooth projective varieties over a field (of characteristic not 2). I will describe its structure, and give explicit "stable" polynomial generators. I will draw some concrete consequences concerning the geometry of fixed loci of involutions, in terms of Chern numbers. I will in particular mention an algebraic version of Boardman's five halves theorem. |
