Some Processes and Models on Deformed Stochastic Bases

This is a survey of results of the Rostov-on-Don team on the deformed martingales of the 1st and the 2nd kind, Haar interpolations of martingales and their applications. First of all we give discrete-parameter versions of representation theorems and of optional sampling theorems for deformed martingales. Then we discribe Haar interpolation techniques for statical processes. And in the end we explane how complete deformed systems can be investigated with the help of Haar interpolations.
