... Proposition 3 .6. Let (H1) hold. Then (i) ~,~(s, ~, y) and V ~,~(s, x, y) are continuous in (x, y) 9 ~" • ~m, uniformly in s C [0, T] and 6, E >_ O; For fixed 6 > 0 and e > O, ... (s, x, y) and Va'~(s,x,y) are continuous in (s,x,y) 9 [0, T] x Rn • Rm. (ii) For 6 > 0 and ~ >_ O, Va'e(s, x, y) is the unique viscosity solution of (3.25), and for 6, r > ... to (s, x, y) and Z(.) - z.
