HIGHLIGHTS
- who: IRWIN E. SCHOCHETMAN from the (UNIVERSITY) have published the research: A CHARACTERIZATION OF OPEN MAPPING IN TERMS OF CONVERGENT SEQUENCES, in the Journal: (JOURNAL) of 22/01/2006
- what: In this research/expository note the authors show that a mapping is open if and only if the set-valued inverse mapping preserves convergent sequences in an appropriate set-theoretic sense.
SUMMARY
By definition, f is open if f (U) is open in Y, whenever U is open in X. Does there exist a characterization of openness for f in terms . . .
