Pat, (01)
"Well you did ask," :-) I could say that studies show that singing to my
plants (music, gardening and botany) helps them grow. On a more serious note I
would like a good intro to category theory as you have defined it here
pertaining to math: "Category theory is a branch of pure
mathematics, a kind of ultimate abstraction of algebra, which focusses
on systems ('categories') defined by mappings " (02)

Well, you did ask. These three topics have absolutely nothing whatever
to do with one another. Gauge theories focus on symmetries in physical
theory: that is, ways in which theories are invariant under various
mathematical transformations. Category theory is a branch of pure
mathematics, a kind of ultimate abstraction of algebra, which focusses
on systems ('categories') defined by mappings . Semantics is concerned
with the relationship between representations and what it is that they
represent. One might as well ask for comments on a possible
relationship between botany, music and gardening. (07)
Let me ask in return, what was it that suggested to you that these
three topics might have any relationship? (08)
