Polynomially convex hulls with piecewise smooth boundaries. (English) Zbl 0585.32016
We prove that for certain class of two-dimensional, smoothly embedded, totally real submanifolds M of $${\mathbb{C}}^ 2$$ the polynomially convex hull $$\hat M$$ of M is the union of images of smoothly embedded analytic disks in $${\mathbb{C}}^ 2$$ with boundaries in M. The boundary of $$\hat M$$ is piecewise smooth and is foliated by such disks. Our proof is based on a result of H. Alexander and J. Wermer [Math. Ann. 271, 99-109 (1985; Zbl 0538.32011)) and Slodkowski (to appear) who proved, in a slightly more general setting, that $$\hat M$$ is the union of images of bounded analytic disks.
