Perfect Powers with Three Digits

چکیده
We solve the equation xa + xb + 1= yq in positive integers x, y, a, b and q with a > b and q > 2 coprime to φ(x). This requires a combination of a variety of techniques from effective Diophantine approximation, including lower bounds for linear forms in complex and p-adic logarithms, the hypergeometric method of Thue and Siegel applied p-adically, local methods, and the algorithmic resolution of Thue equations. §

Perfect Powers with Few Ternary Digits
We classify all integer squares (and, more generally, q-th powers for certain values of q) whose ternary expansions contain at most three digits. Our results follow from Padé approximants to the binomial function, considered 3-adically.

متن کاملPerfect Powers with Few Binary Digits and Related Diophantine Problems
We prove that, for any fixed base x ≥ 2 and sufficiently large prime q, no perfect q-th powers can be written with 3 or 4 digits 1 in base x. This is a particular instance of rather more general results, whose proofs follow from a combination of refined lower bounds for linear forms in Archimedean and non-Archimedean logarithms.

We prove that if q 5 is an integer, then every qth power of an integer contains at least 5 nonzero digits in its binary expansion. This is a particular instance of one of a collection of rather more general results, whose proofs follow from a combination of refined lower bounds for linear forms in Archimedean and non-Archimedean logarithms with various local arguments.

Friends of Grover Powers. The late Daniel Darrow, a long-time and dis. tinguished member of your faculty, in 1946, on dedicating his first 76 sci. entific papers in a bound volume to Grover Powers, inscribed it as follows: "To Grover F. Powers, whose faith in people made this work possible." Faith in people is perhaps the best way to characterize Grover Powers' basic attitude in life and this f...
