DESCRIPTION:The Deligne-Mumford-Knudsen moduli space of n-pointed stable c
 urves of genus 0 is a smooth projective variety of dimension n - 3. We con
 struct an integral isomorphism from its Grothendieck ring of vector bundle
 s to its Chow cohomology ring which satisfies a Hirzebruch-Riemann-Roch-ty
 pe formula. This isomorphism\, which is unrelated to the Chern character\,
  can be used to reduce many K-theoretic computations to easier problems in
  intersection theory. Joint with Shiyue Li\, Sam Payne\, and Nick Proudfoo
