I will report on joint work with Olga Trapeznikova, on a new proof of the Verlinde formula for parabolic moduli spaces.
The proof only uses the basics of invariant theory and carries out a program initiated by Michael Thaddeus on following the changes of Euler characteristics of line bundles when crossing GIT walls.
The necessary combinatorics is controlled by so-called diagonal bases of the relevant hyperplane arrangements.
