Abstract :
In this paper, it is proved that the product system (X × Y, T × S) is multi-F -sensitive (resp., (F1, F2)- sensitive) if and only if (X, T ) or (Y, S) is multi-F -sensitive (resp., (F1, F2)-sensitive) when Furstehberg families F and F2 have the Ramsey property, improving the main results in [N. Degirmenci, S. Kocak, Turk. J. Math., 34 (2010), 593–600] and [R. Li, X. Zhou, Turk. J. Math., 37 (2013), 665–675]. Moreover, some analogical results for semi-flows are obtained.
