报告摘要  Abstract

We discuss an extension  of Quine’s bound on the number of self-intersection of curves with polynomial parameterization to the case of Laurent polynomials.  As an application, we show that circle embeddings are dense among all maps from a circle to a plane with respect to an integral norm and, in particular, get some property of the Fourier coefficients of a circle embedding. This is based on a joint work with L.V. Kovalev.
