“…Other extensions of Perron's results for the infinite-dimensional Banach spaces were obtained by J. L. Daleckij, M. G. Krein [2], J. L. Massera, J.J Schäffer [9], [10] and N. van Minh, F. Räbiger, R. Schnaubelt [11]. Some other results concerning the property of stability for the (non)linear skewproduct three-parameter semiflows in the framework of infinite-dimensional Banach spaces were also obtained by C. Stoica, M. Megan [20], C. Preda, P. Preda, A. P. Petre [16] and P. V. Hai [3], [4]. Definition 2.1.…”
