On the construction of a family of transcendental valued infinite products. (English) Zbl 1062.11048
The main result of this paper is the following:
Theorem: Suppose $$\{a_n\}_{n=1}^\infty$$ is a sequence of positive integers greater than unity and such that, for a fixed $$K>2$$ $\liminf_{n\to \infty}\frac{a_{n+1}}{a_n^{K+1}}>2,$ then the infinite product $$\prod_{n=1}^\infty (1+\frac 1{a_n})$$ converges to a transcendental number.
The proof is based on Roth’s theorem. Some examples involving Fibonacci and Lucas sequences are included.
