Abstract:

In this paper, we investigate the following abstract multi-term fractional differential equation
Dtαnut)+AjDtαju(t)=ADtαu(t)+f(t),t∈(0,τ),
where n∈N\{1}, A and A1,…,An-1 are closed linear operators on a complex Banach space E, 0≤α1<…<αn, 0≤α<αn, 0<τ≤∞, f(t) is an E-valued function, and Dtα denotes the Riemann-Liouville fractional derivative of order α ([5]). We introduce and systematically analyze several new types of k-regularized (C1,C2)-existence and uniqueness (propagation) families for (0.1), continuing in such a way our previous researches raised in [22, 24-25] and [34]. Plenty of various examples illustrates our abstract results.

Key words: Abstract multi-term fractional differential equations, Riemann-Liouville fractional derivatives, (a,k)-Regularized C-resolvent families, Well-posedness
