Theorem	hdmapval 37120*	Value of map from vectors to functionals in the closed kernel dual space. This is the function sigma on line 27 above part 9 in [Baer] p. 48. We select a convenient fixed reference vector E to be <. 0 , 1 >. (corresponding to vector u on p. 48 line 7) whose span is the lattice isomorphism map of the fiducial atom P = ( ( oc ` K ) ` W ) (see dvheveccl 36401). ( J ` E ) is a fixed reference functional determined by this vector (corresponding to u' on line 8; mapdhvmap 37058 shows in Baer's notation (Fu)* = Gu'). Baer's independent vectors v and w on line 7 correspond to our z that the A. z e. V ranges over. The middle term ( I ` <. E , ( J ` E ) , z >. ) provides isolation to allow E and T to assume the same value without conflict. Closure is shown by hdmapcl 37122. If a separate auxiliary vector is known, hdmapval2 37124 provides a version without quantification. (Contributed by NM, 15-May-2015.)
