Clark–Ocone type formula for non-semimartingales with finite quadratic variation

Abstract: We provide a suitable framework for the concept of finite quadratic variation for processes with values in a separable Banach space B using the language of stochastic calculus via regularizations, introduced in the case B = R by the second author and P. Vallois. To a real continuous process X we associate the Banach valued process X(·), called window process, which describes the evolution of X taking into account a memory τ > 0. The natural state space for X(·) is the Banach space of continuous functions on [−… Show more

“…Elements of calculus via regularization were extended to (real) Banach space valued processes in a series of papers, see e.g. [8,9,10,11]. Two classical notions of stochastic calculus in Banach spaces, which appear in [28] and [13] are the scalar 2 and tensor quadratic variations.…”
