讲座内容：

We solve a question asked by Xu about the order of optimal constants in the Littlewood-Paley-Stein inequality. The argument relies on a construction of a special diffusion semi-group associated to a martingale which relates the Littlewood-Paley g-function with the matingale square function pointwisely. This can also be done in the vector valued and noncommutative cases.
