A Hochschild-Kostant-Rosenberg theorem for cyclic homology

Marcel Bökstedt, Iver Ottosen

Let be a commutative algebra over the field . We show that there is a natural algebra homomorphism which is an isomorphi…

Pairs of pants, Pochhammer curves and -invariants

Marcel Bökstedt, Nuno M. Romão

We propose an intuitive interpretation for nontrivial -Betti numbers of compact Riemann surfaces in terms of certain loops in embedded pairs of pants. This description uses tw…

Cobordism obstructions to independent vector fields

Marcel Bökstedt, Johan L. Dupont, Anne Marie Svane

We define an invariant for the existence of r pointwise linearly independent sections in the tangent bundle of a closed manifold. For low values of r, explicit computations of the…

On the curvature of vortex moduli spaces

Marcel Bökstedt, Nuno M. Romão

We use algebraic topology to investigate local curvature properties of the moduli spaces of gauged vortices on a closed Riemann surface. After computing the homotopy type of the un…

On cyclic fixed points of spectra

Marcel Bökstedt, Robert R. Bruner, Sverre Lunøe--Nielsen +1

For a finite p-group G and a bounded below G-spectrum X of finite type mod p, the G-equivariant Segal conjecture for X asserts that the canonical map X^G --> X^{hG} is a p-adic equ…

The suspended free loop space of a symmetric space

Marcel Bokstedt, Iver Ottosen

Let M be one of the projective spaces CP^n, HP^n for n>1 or the Cayley projective plane OP^2, and let LM denote the free loop space on M. Using Morse theory methods, we prove that…
