In this work, we give a sufficient algebraic condition for the local observability problem of invariant control systems on compact Lie groups such that the output map is not differentiable. In particular, the usual techniques involving Lie derivatives do not work. Our approach comes from the represe
We show under MA(σ -centered) the existence of at least (2 ω ) + non-homeomorphic topological group topologies on the free Abelian group of size 2 ω which make it countably compact and separable. In particular, under GCH the maximum possible number of such topologies is attained. As a corollary, we
