On a generalized notion of metrics
Wolf-Jürgen Beyn
In these notes we generalize the notion of a (pseudo) metric measuring the distance of two points, to a (pseudo) n-metric which assigns a value to a tuple of n points. We present t…

Smoothness properties of principal angles between subspaces with applications to angular values of dynamical systems
Wolf-Jürgen Beyn, Thorsten Hüls
In this work we provide detailed estimates of maximal principal angles between subspaces and we analyze their smoothness for smoothly varying subspaces. This leads to a new definit…
