The goal of this paper is to construct canonical Lévy area
processes for Banach space valued Brownian motions via dyadic approximations.
The significance of the existence of canonical Lévy area processes is
that a (stochastic) integration theory can be established for such Brownian
motions (in Banach spaces). Existence of flows for stochastic differential
equations with infinite dimensional noise then follows via the results of Lyons
and Lyons and Qian. This investigation involves a careful analysis on the
choice of tensor norms, motivated by the applications to infinite dimensional
stochastic differential equations.
