Higher-dimensional flying wing Steady Ricci Solitons
Pak-Yeung Chan, Yi Lai, Man-Chun Lee
For any , we construct an -parameter family of steady gradient Ricci solitons with non-negative curvature operator and prescribed by the eigenvalues of Ricci tensor…
Local mollification of metrics with small curvature concentration
Man-Chun Lee, Tang-Kai Lee
In this work, we establish a local smoothing result on metrics with small curvature concentration with respect to Sobolev constants and volume growth. In contrast with all previous…
Gap Theorem on locally conformally flat manifold
Ming Hsiao, Man-Chun Lee
In this work, we study a gap phenomenon in locally conformally flat Riemannian manifolds with non-negative Ricci curvature. We construct complete solutions to the Yamabe flow that…
On the weakly conical expanding gradient Ricci solitons
Pak-Yeung Chan, Man-Chun Lee
In this work, we construct several sequences of metrics on sphere with different limiting behaviors. By combining with the work of Deruelle, we use it and the localized maximum pri…
