INDEX OF NAMES AN D SUBJECTS To keep the number of page references for any given item down to a usable size, the index contains no explicit references to terms when they are used in proofs. However, it does contain references to authors whose works are cited in proofs. A boldface number indicates a principal reference, or a reference to a definition.
