Poincaré duality in Hochschild (co)homology [PDF]

, 2006
These are notes on van den Bergh’s analogue of Poincar´e duality in Hochschild (co)homology [VdB98]. They are based on survey talks that I gave in 2006 in G¨ottingen, Cambridge and Warsaw and consist of an elementary explanation of the proof in terms ...

Cyclic cohomology after the excision theorem of Cuntz and Quillen [PDF]

, 2013
The excision theorem of Cuntz and Quillen established the existence of a six term exact sequence in the bivariant periodic cyclic cohomology HP*(–,–) associated with an arbitrary algebra extension 0 ? S ? P ? Q ? 0.

One the P-Adic Local Invariant Cycle Theorem [PDF]

, 2012
The aim of this paper is to consider the $p$-adic local invariant cycle theorem in the mixed characteristic case. In the first part of the paper, via case-by-case discussion, we construct the $p$-adic specialization map, and then write out the ...

A new description of equivariant cohomology for totally disconnected groups [PDF]

, 2008
We consider smooth actions of totally disconnected groups on simplicial complexes and compare different equivariant cohomology groups associated to such actions.

Quadratic forms and linear algebraic groups [PDF]

, 2009
Topics discussed at the workshop Quadratic Forms and Linear Algebraic Groups included besides the algebraic theory of quadratic and Hermitian forms and their Witt groups several aspects of the theory of linear algebraic groups and homogeneous varieties ...

Global Solvably Closed Anabelian Geometry [PDF]

, 2006
In this paper, we study the pro-Σ anabelian geometry of hyperbolic curves, where Σ is a nonempty set of prime numbers, over Galois groups of “solvably closed extensions” of number fields — i.e., infinite extensions of number fields which have ...

Monoidality of Franke's exotic model [PDF]

, 2011
We discuss the monoidal structure on Franke's algebraic model for the K_{(p)} -local stable homotopy category at odd primes and show that its Picard group is isomorphic to the ...

Chern character for totally disconnected groups [PDF]

, 2009
In this paper we construct a bivariant Chern character for the equivariant $ KK $-theory of a totally disconnected group with values in bivariant equivariant cohomology in the sense of Baum and Schneider.

Algebraic Cobordism and \'Etale Cohomology [PDF]

, 2022
Thomason's \'{e}tale descent theorem for Bott periodic algebraic $K$-theory \cite{aktec} is generalized to any $MGL$ module over a regular Noetherian scheme of finite dimension.

On Finiteness Properties of Local Cohomology Modules [PDF]

, 2022
openThis thesis has its foundations in the fields of homological and commutative algebra, in particular in the study of local cohomology. Local cohomology was introduced by Grothendieck in the early 1960s, in part to answer a conjecture of Pierre Samuel ...
