  • Title: Stopped CCR-flows and Isometric co-cycles
  • Abstract :  The CCR-flows give the simplest example of a semigroup of endo-morphisms of the *-algebra of the set of all bounded linear operators in the Fock-space over  L^2(R_+), which enjoys the continuous tensor-product decomposition property  and thus produces the simplest example of  the so-called product systems. Using a “sto-time” in the Fock space one constructs a large class  of  new ” CCR-flows” ,each carrying  its own “product-system” .  Similarly,isometric evolutions in Fock space  can also be stopped with respect to a given stop-time .
