- A solution of (2.1) and (2.4) is denoted by x(o) and we assume in the following that x((f>o) exists and is unique on [?_i, oo). Remark!.].. It is known (see, e.g., ...
- If xi = yi for all i ? {1, . . . , n}, then the inequality (1) holds with equality, hence we may assume in the following that xi ? yi for at least one i. If xi = yi for an i ? {1, ...
- such a condition we mention the following, that /(x,X) may be uniformly approximated to by a sequence of functions. /i(x,X), each of which is integrable with ...
- Show that the functions ? and ?n are continuous and that the function un id of class C2. c. Write the Itô formula for un(Bt). We will admit in the following that x ? R ...

- Since x ? C
- follows that (x, y) /? R and (y, z) /? R, and hence xR/y and yR/z. By the contrapositive of the antitransitive property we have that xR/z. Hence. (x, z) /? R and (x, ...
- classes. If x1 ? [x], then x1 ? z and z ? y, so x1 ? y by the transitivity of ?, and therefore x1 ? [y]. It follows that [x] ? [y]. A similar argument applied to y1 ? [y].
- B, it follows that x ? C. Since x ? A and x ? C, it follows that x ? A n C. Since x ? A n C and x /? B, it follows that x ? (A n C)
- B. We now show ...
- appear to merge into one. Compare the clarity of the following examples. Because x2 ?1 = 0, x = 1 or x = ?1. ×. Because x2 ?1 = 0, it follows that x = 1 or x = ?1.
