Optimal domains for \(L^{0}\)-valued operators via stochastic measures. (English) Zbl 1148.46026
Let \(T:E\to L^0([0,1])\) be a linear operator, where \(E\) is a function space and \(L^0([0,1])\) the space of measurable functions with the topology of convergence in measure. The authors study conditions on \(T\) and \(E\) that allow them to extend the operator \(T\) to domains larger than \(E\) and in this case to study the properties of such domains.
