DESCRIPTION:The Planck satellite has recently measured the anisotropies in
  the cosmic\nmicrowave background to unprecedented accuracy.  The data is 
 in excellent\nagreement with the predictions of an early inflationary phas
 e driven by a\nsingle scalar field.  However\, our incomplete knowledge of
  high-energy\nparticle physics naturally leads us to consider the possibil
 ity of multiple\nscalar fields contributing to inflation.  In this talk we
  will review the\nbasic ideas of inflationary cosmology\, emphasizing how 
 multiple\ninflationary fields both enrich the dynamics and create new prob
 lems\, such\nas sensitive dependence to initial conditions.  We will discu
 ss the\nevolution of these scalar fields in an inflating universe and sket
 ch how\nour a prior' belief in their likely initial state affects the conc
 lusions\nwe can draw from these models.\n\nhttps://indico.ific.uv.es/event
