"The mapping is necessarily a continuous function."

This is probably the calculus part. I have never seen a calculus book dealing with linear (or any other) mappings. Also, I've always thought of the mappings as "vector functions", 3 functions in one notation.

"Continuous functions map connected sets to connected
sets and compact sets to compact sets."

And this is probably the topology part. Do there exist books tying calculus and topology together?
