Cohomological and homological spectral sequences are shown to be isomorphic.

The cobordism group N(Mn)N(M^n) of codimension-one immersions in the nn-manifold MnM^n has a natural filtration induced by any cellular decomposition. The problem addressed in this paper is the explicit computation of the graded group grN(Mn)gr^*N(M^n). We introduce some new invariants for immersions enlightening the Atiyah-H…

Degree one twisting of Deligne cohomology, as a differential refinement of integral cohomology, was established in previous work. Here we consider higher degree twists. The Rham complex, hence de Rham cohomology, admits twists of any odd degree. However, in order to consider twists of integral cohomology we need a peri…

Seidel-Smith and Hendricks used equivariant Floer cohomology to define some spectral sequences from symplectic Khovanov homology and Heegaard Floer homology. These spectral sequences give rise to Smith-type inequalities. Similar-looking spectral sequences have been defined by Lee, Bar-Natan, Ozsváth-Szabó, Lipshitz-Tre…
