For classical sets one has with the cumulative hierarchy of sets, with axiomatizations like the system ZF, and with the category SET of all sets and mappings standard approaches toward global universes of all sets. We discuss here the corresponding situation for fuzzy set theory. Our emphasis will be on various approaches toward (more or less naively formed) universes of fuzzy sets as well as on axiomatizations, and on categories of fuzzy sets. What we give is a (critical) survey of quite a lotdoi:10.1007/s11225-006-7197-8 fatcat:vxo5u3lvy5g53ewkj5bdddfa6y
