Abstract

We describe Vaughan Jones’s ground-breaking discovery that symmetries of I I 1 \mathrm {II}_1 factors, as encoded by their subfactors, are quantized and have a natural index that can be non-integral. We then comment on the impact his revolutionary work had in the study of I I 1 \mathrm {II}_1 factors.
