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).
