SUMMARY:A general parametrization of galaxy bias - Fabian Schmidt (MPA Gar
 ching)

DESCRIPTION:I will describe a general and rigorous parametrization of gala
 xy bias\, that is\, of the relation between the density field of a general
  tracer and matter. This bias expansion is complete and non-redundant at a
 ny given order in perturbation theory. This is an essential ingredient for
  the goal of connecting the observed statistics of galaxy clustering with 
 the initial conditions to learn about inflation. Also\, the physical inter
 pretation of the (renormalized) bias parameters can inform models of galax
 y formation.\n
