58. Nest ো࢑੄ ৉ೡ (1) Wilkinson presents three algebraic operators called cross ( ), nest( ), and blend ( ), together with the rules for their use. Theyare derived from the set operators product ( ), discreteunion ( ), and union ( ), respectively. — nVIZn 3p ੿ࠁदпച Ҋ੹ ةࢲ ݽ੐ - The Grammar of Ghapcis 5੢ © nacyot 2015 - 58
59. Nest ো࢑੄ ৉ೡ (2) The disjoint union of two sets A and B, denoted by A B, produces a set whose members are tagged elements. A tagged element is one of the form x:$, where x X is the element and the symbol $ is the tag. A tag is some- times called an identifier or a color; it may be a string, a numerical value, or another piece of information. — GoG 26p ੿ࠁदпച Ҋ੹ ةࢲ ݽ੐ - The Grammar of Ghapcis 5੢ © nacyot 2015 - 59
60. Nest ো࢑੄ ৉ೡ (3) The nesting variable tags the nested variable such that (s, t) implies (s : t). We will not use this notation below, but we will assume an algebra system can identify the nesting elements through a tagging index. — GoG 65p ੿ࠁदпച Ҋ੹ ةࢲ ݽ੐ - The Grammar of Ghapcis 5੢ © nacyot 2015 - 60
