Discuss DM Stacks/Examples Needed

We should include some of the material from http://faculty.missouri.edu/~edidind/Papers/rrforDMstacks.pdf into this article. — Preceding unsigned comment added by 97.122.75.155 (talk) 05:28, 20 July 2017 (UTC)

Certianly. The observation of the paper is simple: for a quotient stack, one can approach Riemann-Roch from the point of view of equivariant intersection theory. This approach is elementary and is especially suitable for concrete calculations. -- Taku (talk) 11:48, 20 July 2017 (UTC)

Another application of GRR is for the computation of an ideal sheaf https://math.stackexchange.com/questions/1749776/chern-class-of-ideal-sheaf
