摘要

The main object of this paper is to establish the Hamiltonian of the Hudson-Parthasarathy quantum stochastic differential equationd(t)U(s)(t) = (-iL(+)dAt - iLdA(t)(+) - L(+)Ldt/2)U-s(t).As its solution forms a cocycle with respect to the time shift, its product with the time shift establishes a strongly continuous one-parameter unitary group W(t) = exp(-itH) and H is called its Hamiltonian. Our main result is that H is the closure of the restriction of the singular operator(H) over cap = i (partial derivative) over cap + L+(a) over cap + L (a) over cap (+)on an appropriate domain that shall be explicitly described. The symmetric differentiation (partial derivative) over cap is a generalization of the generator of the time shift, (a) over cap = a((delta) over cap) and (a) over cap (+) = a(+)(delta) are annihilation and creation operators and S is the symmetric Dirac delta-function. In one dimension the symmetric differentiation might be used to establish a quantum stochastic calculus without Ito term.
