Also we prove the continuation properties of the solution u_? (t) and its fractional derivative D^? u_? (t) in the first two problems as ?>1^- and in the third problem we prove the continuation properties of the solution u_? (t) and its fractional drerivative D^? u_? (t) as ?>1^+ and as ?>2^-. Finally we prove the maximal regularity property of the solution of each problem and give some examples of the three problems.
