Abstract : Let F contained in (R sub n) be closed and A:F maps to (R sub n) be continuous. Assuming that the distance from y+hAy to F is o(h) as h tends to 0 +, it is shown that for each x contained in F the Cauchy problem u prime = Au, u(0) = x, has a solution u: (0, T sub x) maps to F on some interval (0, T sub x), (T sub x > 0.
