Upper estimates on self-perimeters of unit circles for gauges
Horst Martini, Anatoliy Shcherba · Colloquium Mathematicum · 2015
Let $M^2$ denote a Minkowski plane, i.e., an affine plane whose metric is a gauge induced by a compact convex figure $B$ which, as a unit circle of $M^2$, is not necessarily centered at the origin. Hence the self-perimeter of $B$ has two values depen
