Pole inflation in Jordan frame supergravity
  We investigate inflation models in Jordan frame supergravity, in which an
inflaton non-minimally couples to the scalar curvature. By imposing the
condition that an inflaton would have the canonical kinetic term in the Jordan
frame, we construct inflation models with asymptotically flat potential through
pole inflation technique and discuss their relation to the models based on
Einstein frame supergravity. We also show that the model proposed by Ferrara et
al. has special position and the relation between the K\"ahler potential and
the frame function is uniquely determined by requiring that scalars take the
canonical kinetic terms in the Jordan frame and that a frame function consists
only of a holomorphic term (and its anti-holomorphic counterpart) for symmetry
breaking terms. Our case corresponds to relaxing the latter condition.
