DESCRIPTION:Speakers: Bruno Ribeiro (Observatório Nacional)\nWe investiga
 te a possible inflationary scenario where the expantion is driven by a slo
 w evolution homogeneous single scalar field\, whose potential V(φ) is giv
 en by a generalized exponential function taken from the κ-deformed theori
 es. Within the *slow-roll* approximation\, we obtained some the main predi
 ctions of the model\, as scalar spectral index (*ns*)\, tensor to scalar r
 atio (*r*)\, number of *e-folds* (*N*) and the local non-Gaussian paramete
 r (*fNL*). We confront these parameters with the current data of the last 
 mission of Planck satellite\, whose results were analysed and published by
  the *Planck Collaboration*. We show that this model supports a set of sol
 utions with an exponential approach wider than usual and that its theoreti
 cal predictions are compatible with observational data. In particular\, it
  was possible to relieve the tension on *r* between the value predicted by
  the usual exponential model from Ratra and Peebles and the value measured
  by the Planck.\n\nhttps://indico.uni.edu.pe/event/85/contributions/261/
