=+8.5. Call {x}} a subsolution of (8.24) if x; ≤ E,q ,; x, and 0 ≤x, ≤ 1, i € U. Extending Lemma 1, show that a subsolution [x,) satisfies x, So; The solution (0;} of

(8.24) dominates all subsolutions as well as all solutions. Show that if x; = E, q ,;* /

and - 1 x, ≤ 1, then {\x,l) is a subsolution of (8.24).
