Abstract
These notes rigorously construct the stochastic integral of a Hilbert Space valued process driven by a Cylindrical Brownian Motion. We expand upon this stochastic calculus to present an introduction to stochastic differential equations in infinite dimensions, with a particular focus on Stratonovich equations due to their physical importance as well as unbounded noise operators (with applications to transport noise). Furthermore we explore techniques in the existence theory for nonlinear stochastic partial differential equations.
