This is an announcement for the paper "Stochastic integration in Banach spaces using a product structure with partial order" by Joris Bierkens and Onno van Gaans. Abstract: Using a multiplicative structure (for example that of a Banach algebra) and a partial order we construct a weak version of a Banach space valued stochastic integral with respect to square integrable martingales.
