论文摘要
一种身份被得出表达Schur函数作为对成对的Schur $ Q $ functions的总和，从而概括了先前已知的特殊情况。这表明这是从他们的表示形式中作为带电或中性费米子创建和歼灭算子的产品的真空期望值（VEV），Wick的定理以及两种相互抗药性的中性费米子操作员的vev的分解身份。
An identity is derived expressing Schur functions as sums over products of pairs of Schur $Q$-functions, generalizing previously known special cases. This is shown to follow from their representations as vacuum expectation values (VEV's) of products of either charged or neutral fermionic creation and annihilation operators, Wick's theorem and a factorization identity for VEV's of products of two mutually anticommuting sets of neutral fermionic operators.
