چکیده
We prove that the group C ∼ $\widetilde{\mathcal {C}}$ of equivariant concordance directed strongly invertible knots, defined by Sakuma (On Algebraic and topological theories (Kinosaki, 1984), Kinokuniya Company Ltd., Tokyo, 1986, pp. 176–196), is not abelian. do so exhibiting an infinite family non-trivial commutators.

متن کاملEvery Abelian Group Is a Class Group
Let T be the set of minimal primes of a Krull domain A. If S is a subset of T9 we form B = n AP for PeS and study the relation of the class group of B to that of A. We find that the class group of B is always a homomorphic image of that of A. We use this type of construction to obtain a Krull domain with specified class group and then alter such a Krull domain to obtain a Dedekind domain with t...

In this paper, we prove that the group Zp is not a CI-group if n¿ 2p − 1 + ( 2p−1 p ), that is there exist two Cayley digraphs over Zp which are isomorphic but their connection sets are not conjugate by an automorphism of Zp. c © 2002 Elsevier Science B.V. All rights reserved.
متن کاملThe Equivariant Brauer Group of a Group
We consider the Brauer group BM(k, G) of a group G (finite or infinite) over a commutative ring k with identity. A split exact sequence 1 −→ Br′(k) −→ BM′(k, G) −→ Gal(k, G) −→ 1 is obtained. This generalizes the Fröhlich-Wall exact sequence ([7, 8])from the case of a field to the case of a commutative ring, and generalizes the PiccoPlatzeck exact sequence ([13]) from the finite case of G to th...
متن کاملEquivariant Holonomy for Bundles and Abelian Gerbes
This paper generalizes Bismut’s equivariant Chern character to the setting of abelian gerbes. In particular, associated to an abelian gerbe with connection, an equivariantly closed differential form is constructed on the space of maps of a torus into the manifold. These constructions are made explicit using a new local version of the higher Hochschild complex, resulting in differential forms gi...
