Wednesday, 6. December 2017, 15:00 - 16:00
Deniz Karlı's Talk:

 
Singular Integral Operators by Means of Stable Processes and their Connection to Fractional Derivatives  

Abstract: Probability Theory presents tools to study singular integral operators and analitically difficult problems by means of stochastic processes. One such problem is to determine a general class of multipliers and so the bounded operators on function spaces. In this talk we will use a discontinuous process, namely a product of a symmetric stable process and Brownian motion, to show boundedness results of extended versions of classical singular integral operators. We will define Littlewood-Paley operators arising from this process and discuss the corresponding multi- pliers which are studied in [2]. We will introduce versions of intermediate operators appearing in the Littlewood-Paley Theory and show our recent results in [1]. Finally we will discuss the relation between these new operators and fractional derivative in its integral form.
