In 1981, a p-adic interpolation method based on divided differences was derived and was applied to derive, among other things, results on the number of zeros and the bound of certain p-adic exponential polynomials. Here, lower bounds for a p-adic exponential polynomial evaluated over some rational integers are derived using a method of van der Poorten.
Keywords: p-adic exponential polynomial, Turán’s theorem
