The generalized Chaplygin-Jacobi gas
  The present paper is devoted to find a new generalization of the generalized
Chaplygin gas. Therefore, starting from the Hubble parameter associated to the
Chaplygin scalar field and using some elliptic identities, the elliptic
generalization is straightforward. Thus, all relevant quantities that drive
inflation are calculated exactly. Finally, using the measurement on inflation
from the Planck 2015 results, observational constraints on the parameters are
given.
