I agree this is an 'Other' doctrine, and 'nominalism' is a bad name for the doctrine of concretism (i.e., everything is spatiotemporal). But isn't Aristotelianism a form of 'nominalism' as defined here? Doesn't your Aristotelianism deny, or refuse to affirm, any "object that does not correspond to any pattern of matter and energy in space-time"? Properties are not ordinarily thought of as objects, and even so if you think that all properties are instantiated, then they do seem to be spatiotemporal, though perhaps in an informational rather than 'matter/energy' sense. Hm.
