Sigma algebra generated by a partition
WebApr 23, 2024 · Define J = { 1, …, n } − I, then B := ⋃ j ∈ J A j is an element of A. Again, using that the { A 1, …, A n } form a partition of X we have that B = X − A, and so we see that A is … WebThe sigma-algebra ~ is generated by the sequence (S,,),,. It is easy to see that on , f , S admits only one equivalent martingale measure, namely Q. We will now consider the process S under the measure P. On each sigma-algebra ;~', the two measures, P and Q, are equivalent. Suppose now that H" is a sequence of boundedly supported predictable. . . .
