Orbits of Lie Group Actions are Weakly Embedded

Domenico P. L. Castrigiano, Sandra A. Hayes

In this note we prove that whenever a Lie group $G$ acts on a manifold $X$ , then the orbit $G x$ through any point $x$ of $X$ is a weakly embedded submanifold of $X$ . The investigat…

Orthonormal bases of polynomials in one complex variable

D. P. L. Castrigiano, W. Klopfer

Let a sequence $(P_{n})$ of polynomials in one complex variable satisfy a recurre ce relation with length growing slowlier than linearly. It is shown that $(P_{n})$ is an orthonormal…
