Global vs. Local (gauge) Symmetry

[QUOTE="paralleltransport, post: 6571490, member: 589748"] [B]TL;DR Summary:[/B] Let's pick a good definition of gauge "symmetry" Gauge symmetry is highly confusing, partly because many definitions differ in the literature. Strictly speaking gauge symmetry should be called gauge redundancy since you are mapping multiple representations to the same physical state. What is your favourite definition of what "large" gauge vs. "smaller" gauge transformations are? What subtle points do you know about the distinction between a global vs. a local gauge transformation is (any examples)? I'm polling because I have seen conflicting definitions in the literature.
