Abstract:
We propose a method for reducing a deformed stochastic basis of the first kind to a weakly deformed one. In the case when every σ-algebra of a filtration is generated by an at most countable partition of the sample space into atoms, we study the problems of constructing deformations of the first kind from a given density process.
