Let $X$ be a separated scheme of finite type over $k$ with $k$ being a perfect field of positive characteristic $p$. In this work we define a complex $K_{n,X,log}$ via Grothendiecks duality theory of coherent sheaves following Kato and build up a quasi-isomorphism from the Kato-Moser complex of logarithmic de Rham-Witt sheaves $tilde u_{n,X}$ to $K_{n,X,log}$ for the etale topology, and also for the Zariski topology under the extra assumption $k=bar k$. Combined with Zhongs quasi-isomorphism from Blochs cycle complex $mathbb Z^c_{X}$ to $tilde u_{n,X}$, we deduce certain vanishing, etale descent properties as well as invariance under rational resolutions for higher Chow groups of $0$-cycles with $mathbb Z/p^n$-coefficients.
This note contains a generalization to $p>2$ of the authors previous calculations of the coefficients of $(mathbb{Z}/2)^n$-equivariant ordinary cohomology with coefficients in the constant $mathbb{Z}/2$-Mackey functor. The algberaic results by S.Kriz
We propose a new theory of (non-split) P^n-functors. These are F: A -> B for which the adjunction monad RF is a repeated extension of Id_A by powers of an autoequivalence H and three conditions are satisfied: the monad condition, the adjoints conditi
In order to obtain existence criteria for orthogonal instanton bundles on $mathbb{P}^n$, we provide a bijection between equivalence classes of orthogonal instanton bundles with no global sections and symmetric forms. Using such correspondence we are
We reformulate the problem of bounding the total rank of the homology of perfect chain complexes over the group ring $mathbb{F}_p[G]$ of an elementary abelian $p$-group $G$ in terms of commutative algebra. This extends results of Carlsson for $p=2$ t
We compute the $GL_{r+1}$-equivariant Chow class of the $GL_{r+1}$-orbit closure of any point $(x_1, ldots, x_n) in (mathbb{P}^r)^n$ in terms of the rank polytope of the matroid represented by $x_1, ldots, x_n in mathbb{P}^r$. Using these classes and
