Abstract:We present a definition of twisted motivic Chern classes for singulars pairs (X, ∆) consisting of a singular space X and a Q-Cartier divisor containing the singularities of X. The definition is a mixture of the construction of motivic Chern classes previously defined by Brasselet-Schürmann-Yokura with the construction of multiplier ideals. The twisted motivic Chern classes are the limits of the the elliptic classes defined by Borisov-Libgober. We show that with a suitable choice of the divisor ∆ the twisted mo… Show more
