On the invariant surface area functionals in 3-dimensional CR geometry
Pak Tung Ho
Cheng, Yang, and Zhang have studied two invariant surface area functionals in 3-dimensional CR manifolds. They deduced the Euler-Lagrange equations of the associated energy functio…
Constructing -Angenent curve by flow method
Pak Tung Ho
Using a modified curve shortening flow, we construct -Angenent curve, which was first constructed by the shooting method.
New curvature characterization for the weighted Sasaki sphere
Pak Tung Ho, Kuang-Ru Wu
In this paper, we use the shifted cones introduced by Yang and Zhang to classify Sasaki manifolds. This gives a new curvature characterization for the weighted Sasaki sphere.
Convergence of the fractional Yamabe flow for arbitrary initial energy
Jingeon An-Lacroix, Hardy Chan, Pak Tung Ho
Since the seminal paper of Graham and Zworski (Invent. Math. 2003), conformal geometric problems are studied in the fractional setting. We consider the convergence of fractional Ya…
