Titel:
Algebraic Methods for Computing Smallest Enclosing and Circumscribing Cylinders of Simplices 
Abstract:
We provide an algebraic framework to compute smallest enclosing and smallest circumscribing cylinders of simplices in Euclidean space n. Explicitly, the computation of a smallest enclosing cylinder in 3 is reduced to the computation of a smallest circumscribing cylinder. We improve existing polynomial formulations to compute the locally extreme circumscribing cylinders in 3 and exhibit subclasses of simplices where the algebraic degrees can be further reduced. Moreover, we generalize these effic...    »
