Stochastic Calculus for Convoluted Lévy Processes
نویسنده
چکیده
Abstract. We develop a stochastic calculus for processes which are built by convoluting a pure jump, zero expectation Lévy process with a Volterra-type kernel. This class of processes contains, for example, fractional Lévy processes as studied in Marquardt (2006b). The integral which we introduce is a Skorohod integral. Nonetheless we avoid the technicalities from Malliavin calculus and white noise analysis, and give an elementary definition based on expectations under change of measure. As a main result we derive an Itô formula, which separates the different contributions from the memory due to the convolution and from the jumps.

Prediction of fractional convoluted Lévy processes with application to credit risk
Fractional convoluted Lévy processes (fcLps) are introduced by a multivariate componentwise Molchan-Gosolov transformation based on an n-dimensional driving Lévy process. Using results of fractional calculus and infinitely divisible distributions we are able to calculate the conditional characteristic function of integrals driven by fcLps. This leads to important prediction results including th...
متن کاملStochastic Control of Itô-lévy Processes with Applications to Finance
We give a short introduction to the stochastic calculus for ItôLévy processes and review briefly the two main methods of optimal control of systems described by such processes: (i) Dynamic programming and the Hamilton-Jacobi-Bellman (HJB) equation (ii) The stochastic maximum principle and its associated backward stochastic differential equation (BSDE). The two methods are illustrated by applica...
متن کاملAn Anticipative Stochastic Calculus Approach to Pricing in Markets Driven by Lévy Process
We use the Itô-Ventzell formula for forward integrals and Malliavin calculus to study the stochastic control problem associated to utility indifference pricing in a market driven by Lévy processes. This approach allows us to consider general possibly non-Markovian systems, general utility functions and possibly partial information based portfolios. In the special case of the exponential utility...
متن کاملHyperfinite Lévy Processes
A hyperfinite Lévy process is an infinitesimal random walk (in the sense of nonstandard analysis) which with probability one is finite for all finite times. We develop the basic theory for hyperfinite Lévy processes and find a characterization in terms of transition probabilities. The standard part of a hyperfinite Lévy process is a (standard) Lévy process, and we show that given a generating t...
متن کاملCovariance Structure of Parabolic Stochastic Partial Differential Equations with Multiplicative Lévy Noise
We consider parabolic stochastic partial differential equations driven by multiplicative Lévy noise of an affine type. For the second moment of the mild solution, we derive a well-posed deterministic space-time variational problem posed on tensor product spaces, which subsequently leads to a deterministic equation for the covariance function.
