Wei-Norman equations for classical groups via cominuscule induction

J. Gutt, S. Charzyński, M. Kuś

We show how to reduce the nonlinear Wei-Norman equations, expressing the solution of a linear system of non-autonomous equations on a Lie algebra, to a hierarchy of matrix Riccati…

On the minimal number of periodic orbits on some hypersurfaces in $R^{2 n}$

Jean Gutt, Jungsoo Kang

We study periodic orbits on a nondegenerate dynamically convex starshaped hypersurface in $R^{2 n}$ along the lines of Long and Zhu, but using properties of the $S^{1}$ -equiv…

The positive equivariant symplectic homology as an invariant for some contact manifolds

Jean Gutt

We show that positive $S^{1}$ -equivariant symplectic homology is a contact invariant for a subclass of contact manifolds which are boundaries of Liouville domains. In nice cases, whe…
