Stationary discs and geometry of CR manifolds of codimension two

A. Sukhov, A. Tumanov

Research output: Contribution to journalArticlepeer-review


We give a construction of stationary discs and the indicatrix for manifolds of higher codimension which is a partial analog of L. Lempert's theory of stationary discs for strictly convex hypersurfaces. This leads to new invariants of the CR structure in higher codimension linked with the contact structure of the conormal bundle.
