Abstract:
We prove that every one-dimensional real Ambrosio-Kirchheim current with zero boundary (i.e.\ a cycle) in a lot of reasonable spaces (including all finite-dimensional normed spaces) can be represented by a Lipschitz curve parameterized over the real line through a suitable limit of Ces\`{a}ro means of this curve over a subsequence of symmetric bounded intervals (viewed as currents). It is further shown that in such spaces, if a cycle is indecomposable, i.e.\ does not contain ``nontrivial'' subcycles, then it can be represented again by a Lipschitz curve parameterized over the real line through a limit of Ces\`{a}ro means of this curve over every sequence of symmetric bounded intervals, that is, in other words, such a cycle is a solenoid.
