ABSTRACT: The Hida theory of white noise has proved to be a powerful tool in stochastic calculus. An

example is the celebrated Clark-Ocone formula, which is important in mathematical finance.

Moreover, white noise calculus has the advantage that it also works when dealing with issues beyond

the semi-martingale context, for example insider control, control of stochastic Volterra equations etc.

In these lectures we first give a brief introduction to the Hida white noise theory, extended to Lévy

processes and calculus with Wick products and Hida-Malliavin derivatives. Then we apply this

calculus to study some optimal control problems in finance.

The presentation is partly based on joint works with Nacira Agram, Olfa Draouil and Elin Røse, all at

the Department of Mathematics, University of Oslo, Norway and Samia Yakhlef, University of Biskra,

Algeria. The most relevant papers are listed below.
