## Canonical extensions in the algebraic approach to logic

*Sonja Cox (TU Delft)*

Randomised estimates for operators have a long tradition in analysis of Banach spaces, often occurring naturally where the Hilbert space theory calls for uniform estimates. Recently, Van Neerven, Veraar and Weis have demonstrated that randomised estimates for families of operators play an important in the theory of stochastic PDE's in Banach spaces. In my talk I will take another (small) step toward applications: I will demonstrate how the randomised estimates can be obtained which are necessary for the convergence of the Euler scheme for stochastic PDE's in Banach spaces.
