Quasi self-dual exponential L\'evy processes
The important application of semi-static hedging in financial markets naturally leads to the notion of quasi self-dual processes. The focus of our study is to give new characterizations of quasi self-duality for exponential L\'evy processes such that the resulting market does not admit arbitrage opportunities. We derive a set of equivalent conditions for the stochastic logarithm of quasi self-dual martingale models and derive a further characterization of these models not depending on the L\'evy-Khintchine parametrization. Since for non-vanishing order parameter two martingale properties have to be satisfied simultaneously, there is a non-trivial relation between the order and shift parameter representing carrying costs in financial applications. This leads to an equation containing an integral term which has to be inverted in applications. We first discuss several important properties of this equation and, for some well-known models, we derive a family of closed-form inversion formulae leading to parameterizations of sets of possible combinations in the corresponding parameter spaces of well-known L\'evy driven models.
