On strong liftings for projective limits

N. Macheras, W. Strauss (1994)

Fundamenta Mathematicae

Similarity:

We discuss the permanence of strong liftings under the formation of projective limits. The results are based on an appropriate consistency condition of the liftings with the projective system called "self-consistency", which is fulfilled in many situations. In addition, we study the relationship of self-consistency and completion regularity as well as projective limits of lifting topologies.

On option pricing in the multidimensional Cox-Ross-Rubinstein model

Michał Motoczyński, Łukasz Stettner (1998)

Applicationes Mathematicae

Similarity:

Option pricing in the multidimensional case, i.e. when the contingent claim paid at maturity depends on a number of risky assets, is considered. It is assumed that the prices of the risky assets are in discrete time subject to binomial disturbances. Two approaches to option pricing are studied: geometric and analytic. A numerical example is also given.
