On barely continuous functions

Richard Stephens

International Journal of Mathematics and Mathematical Sciences, 1988, vol. 11, 1-5

Abstract:

The term barely continuous is a topological generalization of Baire- 1 according to F . Gerlits of the Mathematical Institute of the Hungarian Academy of Sciences, and thus worthy of further study. This paper compares barely continuous functions and continuous functions on an elementary level. Knowing how the continuity of the identity function between topologies on a given set yields the lattice structure for those topologies, the barely continuity of the identity function between topologies on a given set is investigated and used to add to the structure of that lattice. Included are certain sublattices generated by the barely continuity of the identity function between those topologies. Much attention is given to topologies on finite sets.
