摘 要:
本文利用Gamma分布的n阶矩与半不变量之间的组合关系,在Fock空间的一个稠子空间上定义了一个新的内积,按此内积完备化得到交互作用Fock空间。在此交互作用Fock空间上重新定义了增生,保守,湮灭算子。最后考虑了由三种算子的线性组合所构成的量子Levy-Meixner过程。[著者文摘]

Abstract:
By using the combinatorial relation between the n- th moment and cumulants of an infinitely divisible distribution, we define a new inner product on a dense subspace of Fock space. Completing the subspace with respect to the new inner product we get an interacting Fock space. Then we redefine the creation, conservation,annihilation operators on the interacting Fock space. At last, we construct the Quantum Levy-Meixner processes as a linear combination of the field operators.[著者文摘]
