Abstract

Let m2m\ge 2 be an integer, KK an algebraic number field and αK{0,1}\alpha\in K\setminus \{0,-1\} with sufficiently small absolute value. In this article, we provide a new lower bound for linear form in 1,log(1+α),,logm1(1+α)1,{\rm{log}}(1+\alpha),\ldots,{\rm{log}}^{m-1}(1+\alpha) with algebraic integer coefficients in both complex and pp-adic cases (see Theorem 2.12.1 and Theorem 2.42.4). Especially, in the complex case, our result is a refinement of the result of Nesterenko-Waldschmidt on the lower bound of linear form in certain values of power of logarithms. The main integrant is based on Hermite-Mahler's Pad\'{e} approximation of exponential and logarithm functions.
