Dear all,
The next Banach spaces webinar is on Friday June 5 9AM CDT (e.g., Dallas, TX time). Please join us at
https://unt.zoom.us/j/512907580
Speaker: Denny Leung, National University of Singapore Title: Local convexity in $L^0$.
Abstract. Let $(\Omega,\Sigma,\bP)$ be a nonatomic probability space and let $L^0(\Omega,\Sigma,\bP)$ be the space of all measurable functions on $(\Omega,\Sigma,\bP)$. We present some results characterizing the convex sets in $L^0$ that are locally convex with respect to the topology of convergence in measure. The work is motivated by results of Kardaras & Zitkovic (PAMS 2013) and Kardaras (JFA 2014) and is relevant to mathematical economics/finance.
The talk is based on joint work with Niushan Gao and Foivos Xanthos:
