Outline of Final Research Achievements

Main topic of this research is to find out the asymptotic expansion formula for the Weil-Petersson and the Takhtajan-Zograf metrics near the boundary of Moduli spaces of punctured Riemann surfaces. I have improved the former upper bound estimates of the asymptotic behavior of the Takhtajan-Zograf metric. Around 2015, Mazzeo, Swoboda, Melrose, and Zhu obtained the new proofs and some improvements of my previous estimates of the asymptotics of the Weil-Petersson and the Takhtajan-Zograf metrics. I discussed their new approaches with them, and now am working in unifying their and my techniques to get the complete expansion formulas.
