https://doi.org/10.1007/3-540-35004-7We give a review of results on the operator-norm convergence of the Trotter product formula on Hilbert and Banach spaces, which is focused on the problem of its convergence rates. Some recent results concerning evolution semigroups are presented in details.

https://doi.org/10.1007/978-0-387-73512-2The nondiscrete version of Lassonde-Revalski Fragmentability Principle (Proc. Amer. Math. Soc., 133 (2005), 2637–2646) is equivalent with the Bernays-Tarski Dependent Choice Principle; and as such, equivalent with Ekeland’s Variational Principle (J. Math. Anal. Appl., 47 (1974), 324–353).
