设P和Q是非零的整系数多项式,Q的所有根都是有理数,且对任意n ∈ N,Q(n)≠ 0.设q ∈ Z,|Q| ≥ 2,且令α ∈ Q*.本文证明了数的无理数,并由此导出了Q上Tschakaloff函数Ta(x)=,Ta(x)=,Ta(x)=的导数和Ta(x)=的基元在x = α处的值的线性无关结果。证明使用洛克斯顿和货车德Poorten的马勒的超越方法,这导致,在这种情况下,只有非理性的结果。
Let P and Q be non-zero polynomials with integer coefficients; suppose that all the roots of Q are rational numbers, and that Q(n) ≠ 0 for every n ∈ N. Let q ∈ Z, with |q| ≥ 2, and let α ∈ Q*. We prove that the numberis irrational.From this we deduce linear independence results over Q for the values at x = α of Tschakaloff's function Ta(x) =, of its derivatives, and of its primitives. The proof uses Loxton and Van der Poorten's extension of Mahler's transcendence method, which leads, in this case, only to irrationality results.
