Notes on various topics

• Real representations of some finite groups (including character tables and other properties)
• Bifurcations with dihedral symmetry (mostly pictures)
• Notes on circulant matrices (4 pages: the relation between circulant matrices and symmetry)
• Relative Equilibria and Conserved Quantities in Symmetric Hamiltonian Systems (notes from a Summer School in 1998)
• Symmetric Hamiltonian Bifurcations (coauthors: P.L. Buono & F. Laurent-Polz -- from another Summer School in 2001; some overlap with previous notes)
• Notes on lifting group actions (Given an action of a connected group on a manifold, to what extent can the action be lifted to the universal cover of the manifold?)
• Much on point vortices
