A note on Kunen
Both of Kunen's textbooks use nonstandard notation. The most important deviations are:- R(α) denotes the levels of the cumulative hierarchy of sets, normally denoted by Vα
- ON denotes the class of Ordinals
- HF denotes the set of "hereditarily finite sets", usually denoted by Vω
- ZC denotes ZFC − Replacement. Z denotes ZF − Replacement. ZFC − is ZFC − Foundation and ZF − is ZF − Foundation.
