Abstract
We study -flimsy spaces, which are the topological spaces that remain connected when removing fewer than points but become disconnected when removing exactly points. We show that no such space exists for , and that the compact -flimsy spaces are precisely the dense and order-complete cyclically ordered sets equipped with their order topology. Furthermore, we examine variants of the definition obtained by replacing connectedness by path-connectedness, where paths are either parametrized by or by arbitrary compact linear continua.
