**Optional projection in duality**

*** ** Monday 19 March 2018, 15:15, M203

In this talks we characterize topological duals of Frechet spaces of stochastic processes. This is done by analyzing the optional projection on spaces of cadlag processes whose pathwise supremum norm belongs to a given Frechet space of random variables. We employ functional analytic arguments that unify various results in the duality theory of stochastic processes and also yields new ones of both practical and theoretical interest. In particular, we find an explicit characterization of dual of the Banach space of adapted cadlag processes of class (D). When specialized to regular processes, we obtain a simple proof of a result of Bismut on projections of continuous processes.

Aalto Stochastics & Statistics Seminar

**Teaching meeting**

*** ** Tuesday 20 March 2018, 14:15, Coffee room

Sylvester Eriksson-Bique (UCLA)

**A New proof of Keith-Zhong self improvement**

*** ** Wednesday 21 March 2018, 12:15, M3 (M234)

I will discuss how some curve based ideas lead to a fairly
simple proof of Keith-Zhong self improvement with also simple bounds for
the quantity of self improvement. Additionally I will discuss briefly
some ways these ideas work in other contexts.
