Intersection Cohomology of S1-actions on Pseudomanifolds
For any smooth free action of the unit circle S in a manifold M ; the Gysin sequence of M is a long exact sequence relating the DeRham cohomologies of M and its orbit space M/S. If the action is not free then M/S is not a manifold but a stratified pseudomanifold and there is a Gysin sequence relating the DeRham cohomology of M with the intersection cohomology of M/S. In this work we extend the ...
متن کاملQ-Exact Actions for BF Theories
The actions for all classical (and consequently quantum) BF theories on n-manifolds is proven to be given by anti-commutators of hermitian, nilpotent, scalar fermionic charges with Grassmann-odd functionals. In order to show this, the space of fields in the theory must be enlarged to include “mass terms” for new, non-dynamical, Grassmann-odd fields. The implications of this result on observable...
متن کاملSmooth S Actions on Homotopy Complex Projective Spaces and Related Topics
0. Introduction and motivation. We begin by listing some questions and remarks which establish the theme of this paper. 1. Which cobordism classes of oriented manifolds admit nontrivial circle actions? Answer: Atiyah-Hirzebruch [4]: For a compact oriented manifold X of dim 4k, its sd genus vanishes iff there is a multiple mX which is cobordant to X with W2(Y) = 0, which admits a nontrivial circ...
متن کاملDifferentiable Z9 Actions on Homotopy Spheres
The results of [4] proved that many exotic spheres do not admit smooth actions of relatively high-dimensional compact Lie groups (all group actions considered in this paper are assumed to be effective). It was clear that stronger results should hold in certain cases, and this was confirmed in [5]. A notable feature of [5] is the use of nonexistence theorems for certain smooth circle actions to ...
متن کاملSome Cyclic Group Actions on Homotopy Spheres
In [4J Orlik defined a free cyclic group action on a homotopy sphere constructed as a Brieskorn manifold and proved the following theorem: THEOREM. Every odd-dimensional homotopy sphere that bounds a para-llelizable manifold admits a free Zp-action for each prime p. On the other hand, it was shown ([3J) that there exists a free Zp-action on a 2n-1 dimensional homotopy sphere so that its orbit s...
