Misha Gavrilovich: Lifting properties in point-set topology as instances of "category-theoretic" negation

We observe that some natural mathematical definitions are lifting properties relative to simplest counterexamples, namely the definitions of surjectivity and injectivity of maps, as well as of being connected, separation axioms T0 and T1 in topology, having dense image, induced (pullback) topology, and every real-valued function being bounded (on a connected domain). We try to suggest a way to read off these lifting properties from the text of the usual definitions.

We also suggest that these observations may be used to construct a weak "combinatorial" calculus (formal derivation system) able to prove some implications between topological properties.

The talk is based on [De Morgan Gazette, 2014,  http://mishap.sdf.org/mints-lifting-property-as-negation-DMG_5_no_4_2014.pdf ]
