Query: Hillclimbing inflation   We propose a new class of inflationary models in which inflation takes place
while the inflaton is climbing up a potential hill due to a coupling to
gravity. We study their attractor behavior, and investigate its relation with
known attractors. We also discuss a possible realization of this type of models
with the natural inflation, and show that the inflationary predictions come
well within the region consistent with the observation of the cosmic microwave
background.
