You can electronically access several of my recent reports. Here is the list. The links are to .ps files.

- `On the Dynamics of Ski Skating' (with P. Fink and I. Hentzel), January, 1998.
- `On matrix structures invariant under Toda-like isospectral flows: sign-scaled algebras' (with D. Ashlock and I. Hentzel), September, 1997 (submitted to Linear Algebra and Its Applications).
- `On matrix structures invariant under Toda-like isospectral flows' (with D. Ashlock and I. Hentzel) November, 1995 version, September, 1996 version. We condensed the earlier version to produce the later version. The later version appeared in Linear Algebra and Its Applications 254:29-48.
- `On preserving structured matrices using double bracket operators: tridiagonal and Toeplitz matrices' (with I Hentzel and W. So), May, 1995.
- `On computing eigenvalues and double bracket algebras' (with I. Hentzel), June, 1994 (to appear in the Hadronic Journal).

I can send you copies of my earlier papers.
