DESCRIPTION:\nThere are indications in particle physics as well as in cosm
 ology that underlying theories are scale invariant. All the masses (or mas
 s gaps) including the Planck mass are spontaneously generated in scale inv
 ariant models\, and a set of scalar fields\, which enter cosmic inflation\
 , are commonly involved. In such multi-field systems of inflation\, the in
 flationary parameters may have a large initial-value-dependence\, and more
 over slow-roll conditions are likely violated in certain directions in the
  field space. We consider a particular conformally extended model\, showin
 g how the initial-value-dependence is suppressed and how to use δN formal
 ism for computing the inflationary parameters including the non-Gaussianit
 y parameter despite the violation of  the slow-roll conditions.\n\nhttps:/
