The construction of martingales with given marginal distributions at given times is a recurrent problem in financial mathematics. From a theoretical point of view, this problem is well-known as necessary and sufficient conditions for the existence of such martingales have been described....

A classic paper of Borwein/Lewis (1991) studies optimisation problems over L^p_+ with finitely many linear equality constraints, given by scalar products with functions from L^q. One key result shows that if some x in L^p_+ satisfies the constraints and if the constraint functions are...

A P-sigma-martingale density for a given stochastic process S is a local P-martingale Z>0 starting at 1 such that the … product ZS is a P-sigma-martingale. Existence of a P-sigma-martingale density is equivalent to a classic absence … there exists a P-sigma-martingale density for S. Can we find another P-sigma-martingale density for S having some extra …

In this note, I study further the approach introduced in for the hedging of derivatives in incomplete markets via local risk minimization. A structure result is provided, which essentially shows the equivalence between non-quadratic risk minimization under the historical probability and...
