Abstract |
We extend the transport framework for numerically evaluating the power spectrum and
bispectrum in multi-field inflation to the case of a curved field-
space metric. This method
naturally accounts for all sub and super-horizon tree level effects, including those
induced by
the curvature of the field-space. We present a working open source implementation
of our
equations in an extension of the publicly available PyTransport code. Finally we illustrate the
utility of our work when applied to examples of inflationary models with a non-trivial
field-
space metric. |
