Inflationary study of non-Gaussianity using two-dimensional geometrical
  measures of CMB temperature maps
  In this work we effectively calculated the two-dimensional Minkowski
functionals for cosmic microwave background (CMB) temperature maps generated by
single field models of inflation with a standard kinetic term. We started with
calculation of the bispectrum of initial perturbations and then calculated the
two-dimensional configuration space cubic moments for temperature fluctuations.
These cubic moments give rise to first order non-Gaussian correction terms to
the Minkowski functionals. Thus, we developed a robust mechanism to predict the
amount of non-Gaussianity generated by inflation in the CMB temperature maps
using Minkowski functionals.
