Abstract: We use Bernstein's technique to show that for any fixed , strong solutions of the uniformly parabolic equation in are real analytic in . Here, is a bounded domain and the coefficients are measurable. We also use Bernstein's technique to obtain interior estimates for pure second derivatives of solutions of the fully nonlinear, uniformly parabolic, concave equation in , where is measurable in .
