Examples of It\^o c\`adl\`ag rough paths

Probability 2018-11-14 v2

Abstract

Based on a dyadic approximation of It\^o integrals, we show the existence of It\^o c\`adl\`ag rough paths above general semimartingales, suitable Gaussian processes and non-negative typical price paths. Furthermore, Lyons-Victoir extension theorem for c\`adl\`ag paths is presented, stating that every c\`adl\`ag path of finite pp-variation can be lifted to a rough path.
