Fractional order evolution equations. (English) Zbl 0839.34069

Summary: The author is concerned with the Cauchy problem of the equation \(d^\alpha u(t)/dt^\alpha = Au(t)\), \(t > 0\), \(0 < \alpha \leq 2\), where \(A\) is a closed linear operator defined on the Banach space \(X\). The existence, uniqueness and some other properties of the solution are proved. The continuation of the solution and its derivative (when \(\alpha \to 1)\) to the solution and its derivative of the Cauchy problem of the evolution equation \(du (t)/dt = Au (t)\) are established. As application of the results some different problems of singular integro-differential equations are given.
