摘要:

得到离散时间正规鞅平方可积泛函空间L2(M)中广义计数算子Nh的5种表示:(1)量子Bernoulli噪声(quantum Bernoulli noises,QBN){?k,?k*;k0}的加权表示;(2)Nh的谱表示,广义计数算子Nhh-计数测度#h的值域为其点谱;(3)Nh的“对角化”表示,Nh可表示为L2(M)的标准正交基{Zσ;σΓ}所生成的一维对角化正交投影算子的加权极限;(4)广义Skorohod积分-广义随机梯度表示,Nh可表示为互共轭算子δh?h的复合算子;(5)对N上的任意非负函数h,可构造一列有界广义计数算子,Nh恰为该有界广义计数算子的强极限,当h可和时,Nh为该有界广义计数算子的一致极限。

Abstract:

This paper presents five representations for the generalized number operator Nh defined in L2(M), the space of square integrable functionals in terms of the discrete-time normal martingale, (1) The weighted representation of the quantum Bernoulli noises (QBN) {?k,?k*;k0}; (2) The spectrum representation, the spectrum of Nh is just the range of the h-counting measure #h on Γ; (3) The "diagonalization" representation, i.e., Nh can be expressed as the weighted limit of the one-dimensional diagonalized orthogonal projection operators generated by the QNB {Zσ;σΓ}; (4) The representation in terms of the generalized Skorohod integral-generalized stochastic gradient, specifically, Nh is the composition of the generalized Skorohod δh and its adjoint ?h, the generalized stochastic gradient; (5) For many nonnegative function h on N, a bounded generalized number operators are constructed, which is convergent strongly to Nh and if h is summable, the sequence is convergent uniformly to Nh.
