本文研究了六角系统六重多项式的解析性质。对于芘链,我们证明了六重多项式的零点是真实的,位于开区间,在相应的闭区间是稠密的。我们还表明,系数是对称的,单峰的,对数凹,渐近正常。对于一般的六角系统,我们证明了所有六次多项式的真实的零点在区间上是稠密的,并推测每个六次多项式都有对数凹系数。
In this paper we investigate analytic properties of sextet polynomials of hexagonal systems. For the pyrene chains, we show that zeros of the sextet polynomialsare real, located in the open intervaland dense in the corresponding closed interval. We also show that coefficients ofare symmetric, unimodal, log-concave, and asymptotically normal. For general hexagonal systems, we show that real zeros of all sextet polynomials are dense in the interval, and conjecture that every sextet polynomial has log-concave coefficients.
