There is no degree map for 0-cycles on Artin stacks

arXiv:1208.3239 · doi:10.1007/s00031-013-9225-x

Abstract

We show that there is no way to define degrees of 0-cycles on Artin stacks with proper good moduli spaces so that (i) the degree of an ordinary point is non-zero, and (ii) degrees are compatible with closed immersions.
