New examples of CR submanifolds for the $2$-jet determination problem

Complex Variables 2025-06-27 v1

Abstract

This paper addresses two questions related to mapping problems. In the first part of the paper, we discuss some recent results regarding the 22-jet determination for biholomorphisms between smooth (weakly) pseudoconvex hypersurfaces; in light of those, we formulate a general problem and illustrate it with examples. In the second part of the paper, we provide a new example of a real submanifold of codimension 77 in C10\mathbb{C}^{10} that is not strictly pseudoconvex and for which its germs of CR automorphisms are determined by their 22-jets at a given point.
