Canonical Linear Transformation on Fock Space with an Indefinite Metric
Canonical Linear Transformation on Fock Space with an Indefinite Metric
Canonical fields $?(/) on the Fock space with an indefinite metric < , >= ( ,9 ) and their canonical linear transformations (Bogolyubov transformations) are investigated.Let T be a bijective real linear operator preserving the ^-symplectic form < , / > r = Real ( ,tpj ) in one particle …
