Other Publications and Presentations
The texts listed here have been published under respective conditions or presented at the specified events in the form of a lecture. They include as well some unpublished texts. Depending on the circumstances, they are not always available in three language versions. This also applies to presentation slides. The latter are essentially limited to pictorial statements. The supplementary written explanations have only a quoted character in the PPT versions presented here and therefore only describe the figures in a hinted manner. If necessary, additional explanatory notes can be found in the relevant publication texts.
