The curvature of a Hilbert module over ℂ[z(1), … , z(d)]

A notion of curvature is introduced in multivariable operator theory. The curvature invariant of a Hilbert module over ℂ[z(1), … , z(d)] is a nonnegative real number which has significant extremal properties, which tends to be an integer, and which is hard to compute directly. It is shown that for g...
