DOI: 10.1007/s00233-019-10052-x
Abstract: A direct limit \(S := \lim _\rightarrow S_i\) of semitopological semigroups \(S_i\) is again a semitopological semigroup and so has a weakly almost periodic (WAP) compactification \(S^w\). However, the usefulness of \(S^w\) is limited since… read more here.

DOI: 10.1007/s40840-018-0604-2
Abstract: In this paper, we establish a new existence theorem for asymptotically almost periodic mild solutions to a class of semilinear stochastic evolution equations. As one would expect, our result would generalize and improve some related… read more here.

DOI: 10.1016/j.jde.2017.08.061
Abstract: Abstract We investigate the existence, uniqueness and stability of bounded and almost periodic mild solutions to several Navier–Stokes flow problems. In our strategy, we propose a general framework for studying the semi-linear evolution equations with… read more here.

DOI: 10.1109/tfuzz.2025.3585694
Abstract: This article provides theoretical analysis of the fixed-time multi-almost-periodicity in switched fuzzy neural networks, employing multicontroller strategies and a state-dependent switching mechanism. Utilizing the Ascoli–Arzela theorem, the properties of $M$-matrix, Lyapunov functions method, and some… read more here.
