... Proposition 4.8 in the proof of Proposition 4.4 above. (b) Commuting flows on sequences. Denote by P the set of all sequences {p k } k∈ Z ⊂ P 0 such that the types of all elements of a sequence are pairwise disjoint. Fix ... equal to I. The proof of uniqueness is complete. To prove the existence we note, first of all, that it suffices to provide a proof if one of the κ i ’s is equal to ±1 and one of the δ j ’s is equal ... solutions of isomonodromy problems for such systems of difference equations. In the case of one-interval gap probability this has been done (in a different language) in [Bor], [BB]. One example of the...
