In quantum mechanics, bra–ket notation, or Dirac notation, is used ubiquitously to denote quantum states. The notation uses angle brackets, and , and a vertical bar , to construct "bras" and "kets". A ket is of the form . Mathematically it denotes a vector, , in an abstract (complex) vector space , and physically it represents a state of some quantum system. A bra is of the form . Mathematically it denotes a linear form , i.e. a linear map that maps each vect… WebMar 14, 2003 · Title:Integration of twisted Dirac brackets. Authors:H. Bursztyn, M. Crainic, A. Weinstein, C. Zhu.
