Disconnections of plane continua

Bajguz, W.

Similarity:

The paper deals with locally connected continua X in the Euclidean plane. Theorem 1 asserts that there exists a simple closed curve in X that separates two given points x , y of X if there is a subset L of X (a point or an arc) with this property. In Theorem 2 the two points x , y are replaced by two closed and connected disjoint subsets A , B . Again – under some additional preconditions – the existence of a simple closed curve disconnecting A and B is stated.

Locally connected exceptional minimal sets of surface homeomorphisms

Andrzej Biś, Hiromichi Nakayama, Pawel Walczak (2004)

Annales de l’institut Fourier

Similarity:

We deal with locally connected exceptional minimal sets of surface homeomorphisms. If the surface is different from the torus, such a minimal set is either finite or a finite disjoint union of simple closed curves. On the torus, such a set can admit also a structure similar to that of the Sierpiński curve.
