WebOct 30, 2024 · Di erential cohomology also provides a perspective on the anomaly. The expression F E in (2.9) is valid if there’s electric current but not magnetic current; if j B6= 0, then Fisn’t closed, hence isn’t the curvature of a line bundle. But B is also quantized, hence represents a di erential cohomology class, and we can ask for F to ...

WebIn this paper, the interconnection between the cohomology of measured group actions and the cohomology of measured laminations is explored, the latter being a generalization of the former for the case of discrete group actions and cocycles evaluated on abelian groups. This relation gives a rich interplay between these concepts. Several results can be … Singular cohomology is a powerful invariant in topology, associating a graded-commutative ring with any topological space. Every continuous map f: X → Y determines a homomorphism from the cohomology ring of Y to that of X; this puts strong restrictions on the possible maps from X to Y. Unlike more subtle invariants such as homotopy groups, the cohomology ring tends to be computable in practice for spaces of interest.
WebTake as ( 1, 1) -current the current of integration over one of these two elliptic curves: it is then non-zero closed and positive but since there is no non-trivial H 2 -cohomology, it is also exact.

Each transverse invariant measure determines a cohomology class, by the correspondence ˝ 7!˘7![˘] 2H1(X;R). Recall that the foliation F(!) is minimal if each of its leaves is dense in X.
