Toward pole inflation and attractors in supergravity : Chiral matter
  field inflation
  In string-inspired supergravity theory, K\"{a}hler metric of chiral matter
fields often has a pole. Such K\"{a}hler metric is interesting from the
viewpoint of the framework of the pole inflation, where the scalar potential
can be stretched out to be flat around the pole for a canonically normalized
field and inflation can be realized. However, when K\"{a}hler metric has a
pole, the scalar potential can also have a pole at the same point in
supergravity theory. We study such supergravity models with the pole, and
provide numerical analysis of inflationary dynamics and resultant density
perturbation. In contrast with usual pole inflation models, inflation in this
supergravity based model occurs not on the pole but region apart from the pole.
We show that the existence of the pole in the scalar potential is crucial
nevertheless. We also examine attractor behavior of our model.
