Anwendung der Niggli-Werte zu vergleichenden petrographischen Studien,en zu entwickeln. Dieses System bezieht sich ausschließlich auf die chemischen Verhältnisse und stellt somit keine Gesteinsklassifikation im petrographischen Sinne dar. Es wurde im Jahre 1920 von P. Niggli, teilweise im Anschluß an die Systematik A. Osanns, eingeführt und in der Folge mehrfach übera

Georg Müller,Eckart Braun for problems involvingpoints, lines, polygons, and so on. The field has gainedpopularity very rapidly during the last decade. This ispartly due to the many application areas of computationalgeometry and partly due to the beauty of the field itself.This monograph focuses on three problems that arise
