Abstract

The current status of the recent developments of the second-order gauge-invariant cosmological
perturbation theory is reviewed. To show the essence of this perturbation theory, we concentrate only
on the universe filled with a single scalar field. Through this review, we point out the problems which
should be clarified for the further theoretical sophistication of this perturbation theory. This review
is an extension of the review paper [K. Nakamura, “Second-Order Gauge-Invariant Cosmological
Perturbation Theory: Current Status”, Advances in Astronomy, 2010 (2010), 576273.]. We also
expect that this theoretical sophistication will be also useful to discuss the future developments in
cosmology as a precise science.
