In fact, we should just formulate (in terms of the pay-off function g₀ and the continuous time log-price processes with independent increments) conditions given in Theorems 6.2.5 and 6.2.6 in such way these theorems could be applied to the case of an arbitrary chosen partition Π.

In the case of approximation model with fixed skeleton structure, we should replace fitting conditions L₄ and M₄ by the following more general conditions imposed on transition probabilities and initial distributions of approximating atomic Markov chains Y_Π,ε,n, which ...
