The 2-typical de Rham-Witt complex of the integers

Abstract:

For any ring A and any prime number p there is a construction called the 2-typical de Rham-Witt complex of A. It is related to Milnor's K-theory, Quillen's K-theory, and topological cyclic homology. This algebraic structure was studied and quite well understood for p odd. When p=2 there are a few problems that need to be addressed. I will speak about these and then describe the 2-typical de Rham-Witt complex of the integers.
