In this paper, we deduce a number of eective lower bounds upon the distance to an integer of quantities of the shape b n , where b and n are integers and is a real quadratic irrational. For certain , we obtain inequalities that approach in strength the corresponding ineective results arising from the p-adic version of Roth's theorem. 
Primitive prime divisors in the critical orbit of z^d+c
We prove the finiteness of the Zsigmondy set associated to the critical orbit of f(z) = z^d+c for rational values of c by finding an effective bound on the size of the set. For non-recurrent critical

Let α be a real algebraic number greater than 1. We establish an effective lower bound for the distance between an integral power of α and its nearest integer.
Rational approximation to values of G-functions, and their expansions in integer bases
We prove a general effective result concerning approximation of irrational values at rational points a / b of any G-function F with rational Taylor coefficients by fractions of the form $$n/(B\cdot
