  • Characteristic classes of foliations via SAYD-twisted cocycles 

    Rangipour, Bahram; Sütlü, Serkan (European Mathematical Society, 2015)
    We find the first non trivial “SAYD-twisted” cyclic cocycle over the groupoid action algebra under the symmetry of the affine linear transformations of the Euclidian space. We apply the cocycle to construct a characteristic ...
