我们证明了各种初等齐次对称函数序列是对数凹函数或PF。作为推论,我们证明某些 «/-二项式系数序列和 17-斯特林数具有这些属性。使用的主要技术是使用 Gessel 和 Viennot (G-V 85) 提出的晶格路径对行列式进行组合解释。
We prove that various sequences of elementary and complete ho- mogeneous symmetric functions are log concave or PF. As corollaries we show that certain sequences of «/-binomial coefficients and 17-Stirling numbers have these properties. The principal technique used is a combinatorial interpretation of determinants using lattice paths due to Gessel and Viennot (G-V 85).
