2. Some aspects of these results have been obtained by D.H. Lyth, K.A. Malik, and M. Sasaki, J. Cosmol. Astropart. Phys. 1475-7516 05 (2005) 004. 10.1088/1475-7516/2005/05/004
3. The O(a-2) and O(a-3) terms in the metric have also been found by Y. Tanaka and M. Sasaki, Prog. Theor. Phys. 118, 455 (2007) in the special case of single-field inflation. Their solution is different from that presented in Sec. 3, presumably because they use a different gauge. PTPKAV 0033-068X 10.1143/PTP.118.455
