Research and Projects

For now this page just contains a list of my talks and published documents. A brief description of the individual topics will follow soon. See also my list of publications.

Lazy matrices and rapid development in quantum chemistry

Some slides and posters introducing the molsturm and lazyten projects and how they can be used to yield a modular and flexible quantum-chemistry framework supporting rapid development of new methods.

Note, that in the first few presentations, I use the inital name linalgwrap to refer to the lazy matrix library lazyten.
