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.
