The 1-jet determination of stationary discs attached to generic CR submanifolds
Abstract
The existence of a nondefective stationary disc attached to a nondegenerate model quadric in CN is a necessary condition to ensure the unique 1-jet determination of the lifts of a key family of stationary discs. In this paper, we give an elementary proof of the equivalence when the model quadric is strongly pseudoconvex, recovering a result of Tumanov. Our proof is based on the explicit expression of stationary discs, and opens up a conjecture for the unique 1-jet determination to hold when the model is not necessarily strongly pseudoconvex.
