On the exponential stability and dichotomy of C 0 -semigroups

Phóng Vũ (1999)

Studia Mathematica

Similarity:

A characterization of exponentially dichotomic and exponentially stable C 0 -semigroups in terms of solutions of an operator equation of Lyapunov type is presented. As a corollary a new and shorter proof of van Neerven’s recent characterization of exponential stability in terms of boundedness of convolutions of a semigroup with almost periodic functions is given.

Mild integrated C-existence families

Shen Wang (1995)

Studia Mathematica

Similarity:

We study mild n times integrated C-existence families without the assumption of exponential boundedness. We present several equivalent conditions for these families. Hille-Yosida type necessary and sufficient conditions are given for the exponentially bounded case.
