String topology and cyclic homology
by
Ralph L Cohen(
)
19 editions published in 2006 in English and held by 537 WorldCat member libraries worldwide
The subject of this book is string topology, Hochschild and cyclic homology. The first part consists of an excellent exposition of various approaches to string topology and the ChasSullivan loop product. The second gives a complete and clear construction of an algebraic model for computing topological cyclic homology. The book provides many references for the reader wishing to learn more about the subject, to which it gives a perfect introduction. It is therefore suitable for both graduate students and established researchers. It is certainly the best source of much information that was until now available only to specialists and covers material from the elementary bases to the most recent developments

Algebraic topology : proceedings of an international conference held in Arcata, California, July 27August 2, 1986
by
G Carlsson(
)
5 editions published in 1989 in English and held by 45 WorldCat member libraries worldwide
These are proceedings of an International Conference on Algebraic Topology, held 28 July through 1 August, 1986, at Arcata, California. The conference served in part to mark the 25th anniversary of the journal Topology and 60th birthday of Edgar H. Brown. It preceded ICM 86 in Berkeley, and was conceived as a successor to the Aarhus conferences of 1978 and 1982. Some thirty papers are included in this volume, mostly at a research level. Subjects include cyclic homology, Hspaces, transformation groups, real and rational homotopy theory, acyclic manifolds, the homotopy theory of classifying spaces, instantons and loop spaces, and complex bordism

Algebraic topology and its applications
by
Gunnar E Carlsson(
Book
)
2 editions published in 1993 in English and held by 6 WorldCat member libraries worldwide
In 198990 the Mathematical Sciences Research Institute conducted a program on Algebraic Topology and its Applications. The main areas of concentration were homotopy theory, Ktheory, and applications to geometric topology, gauge theory, and moduli spaces. Workshops were conducted in these three areas. This volume consists of invited, expository articles on the topics studied during this program. They describe recent advances and point to possible new directions. They should prove to be useful references for researchers in Algebraic Topology and related fields, as well as to graduate students

The moduli space of real curves and a Z/2equivariant MadsenWeiss theorem
by Nisan Alexander Stiennon(
)
1 edition published in 2013 in English and held by 1 WorldCat member library worldwide
Galatius, Madsen, Tillmann, and Weiss proved that the classifying space of the category of 2cobordisms is equivalent to the loopspace of a particular Thom spectrum. We show that this is in fact a Z/2equivariant equivalence, where we equip all spaces with a Z/2action which is motivated by complex conjugation of complex curves. In order to do this, we prove an equivariant delooping theorem which shows that grouplike topological monoids with Z/2action are Z/2equivalent to loopspaces. Furthermore, we motivate our choice of Z/2action by showing that it determines a Z/2space BDiff_g whose fixed points classify real curves

Relations among characteristic classes of manifold bundles
by Ilya Grigoriev(
)
1 edition published in 2013 in English and held by 1 WorldCat member library worldwide
We study a generalization of the tautological subring of the cohomology of the moduli space of Riemann surfaces to manifold bundles. The infinitely many "generalized MillerMoritaMumford classes" determine a map R from a free polynomial algebra to the cohomology of the classifying space of manifold bundles. In the case when M is the connected sum of g copies of the product of spheres (S^d times S^d), with d odd, we find numerous polynomials in the kernel of the map R and show that the image of R is a finitely generated ring. Some of the elements in the kernel do not depend on d. Our results contrast with the fact that the map R is an isomorphism in a range of cohomological degrees that grows linearly with g. This is known from theorems of MadsenWeiss and Harer for the case of surfaces (d=1) and from the recent work of Soren Galatius and Oscar RandalWilliams in higher dimensions. For surfaces, the image of the map R coincides with the classical tautological ring, as introduced by Mumford
