Query: The M-theory origin of global properties of gauge theories   We show that global properties of gauge groups can be understood as geometric
properties in M-theory. Different wrappings of a system of N M5-branes on a
torus reduce to four-dimensional theories with $A_{N-1}$ gauge algebra and
different unitary groups. The classical properties of the wrappings determine
the global properties of the gauge theories without the need to impose any
quantum conditions. We count the inequivalent wrappings as they fall into
orbits of the modular group of the torus, which correspond to the S-duality
orbits of the gauge theories.
