Amenable wreath products with non almost finite actions of mean dimension zero
Almost finiteness was introduced in the seminal work of Kerr [J. Eur. Math. Soc. (JEMS) 22 (2020), pp. 3697–3745] as an dynamical analogue of<inline-formula content-type="math/mathml"><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" alttext="script upper Z"><mml:semantics><mml:mrow class="MJX-TeXAtom-ORD"><mml:mi class="MJX-tex-caligraphic" mathvariant="script">Z</mml:mi></mml:mrow><mml:annotation encoding="application/x-tex">\mathcal {Z}</mml:annotation></mml:semantics></mml:math></inline-formula>-stability in the Toms-Winter conjecture.
