The basic properties are presented. The generator and the resolvent of the generator of such semigroups are studied. The compactness of tensor productC-semigroups is also discussed.

Abdelgani 来源：[J].Journal of Semigroup Theory and Applications, 2017, Vol.2018SCIK 摘要：In this paper we find some types of solutions for certain degenerate and non degenerate fractional inverse problems. The main idea of the proofs is based on theory of tensor product of Banach spaces.

Consequently, every subspace in a Banach space is $\varepsilon -$proximinal. Some other results of proximinality in tensor product spaces are given.
