DESCRIPTION:Let X be a smooth projective complex variety. 
\; We prove the comparison between the Gromov-Witt
en invariants of X with their K-theoretic variants
defined by Givental and Lee. \; The key ingre
dient is a virtual Grothendieck-Riemann-Roch formu
la on the moduli stack of stable maps\, which is u
sed to compare Kontsevich&rsquo\;s virtual fundame
ntal class with the one constructed by Behrend-Fan
techi.  \;
