Kostka-Shoji polynomials and Lusztig's convolution diagram

Finkelberg M. V., Ionov A.
We propose an r-variable version of Kostka-Shoji polynomials K−λμ for r-multipartitions λ,μ. Our version has positive integral coefficients and encodes the graded multiplicities in the space of global sections of an ample line bundle over Lusztig's iterated convolution diagram for the cyclic quiver à r−1.
