\u201cFree (Z\/p)^n-complexes\u201d<\/p>\n
Abstract: Carlsson conjectured that the sum of mod-p Betti numbers of a finite, free (Z\/p)^n-CW complex is at least 2^n. For p=2, he connected chain complexes with a free (Z\/p)^n-action to DG modules over a polynomial ring in order to establish lower bounds using commutative algebra and algebraic geometry.<\/p>\n
In this talk, I will report on joint work with Jeremiah Heller on how to extend this connection to commutative algebra to all primes, and on joint work with Henrik R\u00fcping about non-realizability of (Z\/p)^n-equivariant chain complexes.<\/p>\n
