Abstract:
We study rectifiable curves given by mutually singular coordinate
functions in finite-dimensional normed spaces. We describe these
curves in terms of the behaviour of approximative tangents and find
a simple formula for their lengths. We deduce from these results new
necessary and sufficient conditions for the mutual singularity of
finitely many functions of bounded variation.
