New examples of non-locally embeddable CR structures (with no non- constant CR distributions)
We construct examples of non locally embeddable CR structures. These examples may show some improvement on previous examples by Nirenberg, and Jacobowitz and Trèves. They are based on a simple construction which consists in gluing two embedded structures. And (this is our main point) we believe that these examples are very transparent, therefore easy to work with.
