我们用量子力学算符Hermite多项式方法发现了涉及双变数Hermite多项式的二项式的两个定理,它们在计算若干量子光场的物理性质时有实质性的应用.该方法不但具有简捷的优点,而且能导出很多新的算符恒等式,成为发展数学物理理论的一个重要分支.若干常用的特殊函数的宗量也由普通数变为算符.
We propose an operator Hermite polynomial method, namely, to replace the special functions' argument by quantum mechanical operator, and in this way we have derived two binomial theorems related to two-variable Hermite polynomials. This method is concise and may be of help in deducing many operator identities, which may become a new branch in mathematical physics theory.
