    Schwinger-Keldysh formalism. Part II: thermal equivariant cohomology by Felix M. Haehl, R. Loganayagam, Mukund Rangamani

    Published 2017-06-01
    “…In particular, we argue that the structures can be understood in the language of extended equivariant cohomology. To keep the discussion self-contained, we provide a ba-sic review of the algebraic construction of equivariant cohomology and explain how it can be understood in familiar terms as a superspace gauge algebra. …”

    Crystallographic interacting topological phases and equivariant cohomology: to assume or not to assume by Daniel Sheinbaum, Omar Antolín Camarena

    Published 2021-07-01
    “…Using a slightly generalized Bloch decomposition and Grassmanians made out of ground state spaces, we show that the P-equivariant cohomology of a d-dimensional torus gives rise to different interacting phases, where P denotes the point group of the crystalline structure. …”

    Thom polynomials of Morin singularities by Berczi, G, Szenes, A

    Published 2012
    “…We use a combination of the test-curve model of Porteous, and the localization methods in equivariant cohomology. Our formulas are independent of the codimension, and are computationally effective up to d = 6.…”
