  • Title: Introduction to Fractional Calculus (first lecture)
  • Abstract:
It is surprisingly, but most scientists and engineers remain unaware of fractional calculus; it is not being taught in universities and colleges; and others remain sceptical of this field. There are several reasons for that: several of the definitions proposed for fractional derivatives were inconsistent, meaning they worked in some cases but not in others. The mathematics involved appeared very different from that of integer order. There were almost no practical applications of this field. During the last decade fractional calculus has been applied to almost every field of science, engineering, and mathematics. Some of the areas where fractional calculus has made a profound impact.
This course starts from scratch and provides with the background necessary for the understanding of the fractional calculus. It will start from the birth of the fractional calculus. Different approaches defining fractional integral and derivatives will be presented and discussed. Useful and practical properties of each specific fractional derivative will be shown as well. In the end of this two-hour course, there will be some geometric interpretation of fractional derivative to help students have a better understanding of this world.

  • Title: Mean-field and tree interactions for stochastic volatility
  • Abstract:
We shall discuss diffusions with mean-field interactions and interactions through a tree structure by introducing stochastic differential equations with distributional constraints. This class of system includes a system of directed chain stochastic differential equations, and it has an infinite-dimensional feature and so does the corresponding system of filtering equations we discuss. We approximate the system by particle systems, and apply the results for modeling stochastic volatility.
