A Uniform Ergodic Theorem for Commuting Semigroups
Mostafa Mbekhta, Florian-Horia Vasilescu · Journal of the London Mathematical Society · 1998
The existence of the limit, in the uniform topology, of the averages of a finite family of commuting strongly continuous semigroups of bounded linear operators in a Banach space is characterised in terms of infinitesimal generators.
