Two main theorems on well-posedness of this problem in fractional spaces E-alpha are established. In practice, the coercive stability estimates in Holder norms for the solutions of the mixed problems for delay parabolic equations are obtained.en10.1186/1687-2770-2014-126info:eu-repo/semantics/openAccessDelay Parabolic EquationsWell-PosednessFractional SpacesCoercive Stability EstimatesDifferential EquationsNumerical-MethodsStabilityArticleQ1WOS:0003473894000052-s2.0-84901457187Q3
