tween the individual words of a nonmodifiable phrase. For the purposes of decommissioning and recommissioning, the pages of this appendix are taken to precede all other pages in this thesis. All possible symbols, words and phrases constructable are deemed to be commissioned at the start of this appendix. The provisions of this section do not apply to the published paper included verbatim in Appendix F. A.3.8 Precedence of operations The following is a list of the typographical symbols used in this document to denote operations, in order of decreasing precedence. Operators listed consecutively are of the same precedence; steps down the precedence hierarchy are noted explicitly. Operators of the same precedence are evaluated left-to-right, except where noted. The other sections in this appendix should be consulted for details about the operations listed, the language used to describe them, and their notation. Binding symbols: ( ), [ ] and { }. These three sets of symbols, referred to as binding parentheses, binding brackets and binding braces respectively, “bind” symbols together to force precedence. Except where otherwise noted, they are in all mathematical respects equivalent, and hence usable interchangeably; however, certain conventions have emerged, æsthetically pleasing and visually simplifying, such as the use of binding parentheses around three-vector dot products. Binding parentheses, brackets and braces are usually used to force the intended precedence when the non-explicitly-bound expression does not suffice, but they may also be used redundantly for the purposes of emphasis or visual clarity. Symmetrisors: { }. These have the same precedence as binding symbols. See Section A.6.3. Primed quantities: ′ , ′′ . Quantities that are of like form to an original 325
quantity which has been designated a standard symbol, but which must be distinguished from it, may be given the original standard symbol with one, two or more primes. The prime or primes form part of the new symbol, and bind more tightly than any operator listed below. √ The square root symbol: . The quantities appearing underneath the overbar of this symbol are treated as if they lie within an overall binding symbol, and then the positive square root of the result is taken. Matrix indexing: superscripts and subscripts. Matrix indices are deemed to have higher precedence than power-raising superscripts; thus, if x i is a component of a four-vector, then x i 2 is equivalent to (x i ) 2 , without need for the explicit binding. Raising of powers: superscripts. If a superscript does not fall into one of the above categories, and if it is a valid value, then it denotes the raising of the base to the power of the superscript. Powers are evaluated right-to-left (i.e., typographically highest subscript first). If the superscript is rational (but not integral), and the base is real and non-negative, the result is defined to be the positive root; if the base is not real and non-negative, the result is defined by an explanatory note. If the superscript is irrational, and the base is not a non-negative real, the expression is in error. If A is a three-vector, then A 2m ≡ (A ·A) m . If B is a four-vector, then B 2m ≡ (B·B) m . Time-derivatives: overdots. Overdots are used to denote the proper-time or lab-time derivative of a quantity; see Section A.8.20 for details of how the choice of time is decided. Overdots have lower precedence than the symbols above. Thus, ˙σ ′ is defined to be d t σ ′ ; i.e., the prime on σ ′ binds more tightly than the overdot. The scientific-notation symbol: × 10 . The notation x × 10 n , where x is real and n is integral, denotes a real number in scientific notation. Generic multiplication: adjacent symbols. If two symbols are placed next to each other, then they are multiplied together according to the rules appropriate to their particular types. 326
