D(B(t)). We establish stability estimates for the solution of this problem in fractional spaces E?. Also we obtain stability estimates in Höolder norms for the solutions of the mixed problems for delay parabolic equations with Neumann condition with respect to space variables. © 2014 Texas State University - San Marcos.eninfo:eu-repo/semantics/closedAccessDelay Parabolic Equation; Fractional Space; Höolder Norm; Stability EstimateArticle20142-s2.0-84904628654Q3
