On generalized homogeneity of locally connected plane continua

Janusz Jerzy Charatonik (1991)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

The well-known result of S. Mazurkiewicz that the simple closed curve is the only nondegenerate locally connected plane homogeneous continuum is extended to generalized homogeneity with respect to some other classes of mappings. Several open problems in the area are posed.

Monotone homogeneity of dendrites

Janusz Jerzy Charatonik, Włodzimierz J. Charatonik (1997)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

Sufficient as well as necessary conditions are studied for a dendrite or a dendroid to be homogeneous with respect to monotone mappings. The obtained results extend ones due to H. Kato and the first named author. A number of open problems are asked.
