本文建立了一个分析锥面上线性抛物方程的框架,并用它来研究圆锥Ricci流。特别地,我们证明了锥角为一般锥角的锥Ricci流的长时间存在性,并证明了该解具有最优的正则性,即共形因子的时间导数是有界的,并且对于每个固定的时间,共形因子在锥点附近具有显式的渐近展开式.
In this paper, we establish a framework for the analysis of linear parabolic equations on conical surfaces and use them to study the conical Ricci flow. In particular, we prove the long time existence of the conical Ricci flow for general cone angle and show that this solution has the optimal regularity, namely, the time derivatives of the conformal factor are bounded and for each fixed time, the conformal factor has an explicit asymptotic expansion near the cone points.
