Description: Conjugate law for inner product. Postulate (S1) of [Beran] p. 95. Note that is the complex conjugate cjval 13842 of . In the literature, the inner product of and is usually written , but our operation notation co 6650 allows us to use existing theorems about operations and also avoids a clash with the definition of an ordered pair df-op 4184. Physicists use , called Dirac bra-ket notation, to represent this operation; see comments in df-bra 28709. (Contributed by NM, 29-Jul-1999.) (New usage is discouraged.) |
