WebApr 30, 2016 · Consider the 1-form φ = f 2 d f 1. As the path u → π ( ⌊ p ⌋) ( S u) is a weakly geometric rough path, Lemma 4.2 and Lemma 4.3 together states that Φ ( π ( N) ( S ⋅)) can be canonically lifted as a weakly geometric rough path. Moreover, the signature of Φ ( π ( N) ( S ⋅)) is a function of S T.
