This work concerns the description of the topological phases of band insulators of class DIII by using the equivariant cohomology. The main result is the definition of a cohomology class for general systems of class DIII which generalizes the well-known-invariant given by the Teo–Kane formula in the one-dimensional case. In the two-dimensional case, this cohomology invariant allows for a complete description of the strong and weak phases. The relation with the KR-theory, the Noether–Fredholm index and the classification of “Real” gerbes is also discussed.
