Quasi-fredholm and saphar spectrums for the α-times integrated semigroups
We continue to study $α$-times integrated semigroups. Essentially, we characterize the different spectrums of $α$-times integrated semigroups by the spectrums of their generators. Particulary quasi-Fredholm, Kato, essentially Kato, Saphar and essentially Saphar spectrums.
