Chains in CR geometry as geodesics of a Kropina metric
Jih-Hsin Cheng, Taiji Marugame, Vladimir S. Matveev +1
With the help of a generalization of the Fermat principle in general relativity, we show that chains in CR geometry are geodesics of a certain Kropina metric constructed from the C…

Self-dual Einstein ACH metrics and CR GJMS operators in dimension three
Taiji Marugame
By refining Matsumoto's construction of Einstein ACH metrics, we construct a one parameter family of ACH metrics which solve the Einstein equation to infinite order and have a give…
