Thomas Klimpel

My past research interests included differential algebraic equations, nonlinear analysis and relations between symmetries and structural properties.

I recently investigated hierarchical structures, starting from group cohomology, continuing with semi-group theory and ending with lattices and universal algebra.

The above description of me is old. Maybe I will manage to update the "About me" at https://gentzen.wordpress.com/about more frequently.
