The similarity led to the hypothesis that sponges, and, by implication, other animals, evolved from choanoflagellate-like ancest...

We study existence, uniqueness and asymptotic spatial behavior of time-periodic strong solutions to the Navier–Stokes equations in exterior a rigid body, $${\mathscr {B}}$$ , moving by motion given period T, when data are sufficiently regular small. Our contribution improves all previous ones several directions. For example, we allow both translational, $${\varvec{\xi }}$$ angular, $${{\varvec{...
