Abstract:We show that if $k$ is a positive integer, then there are, under certain technical hypotheses, only finitely many coprime positive $k$-term arithmetic progressions whose product is a perfect power. If $4 \leq k \leq 11$, we obtain the more precise conclusion that there are, in fact, no such progressions. Our proofs exploit the modularity of Galois representations corresponding to certain Frey curves, together with a variety of results, classical and modern, on solvability of ternary Diophantine equations.

“…For small values of k, finiteness results for (1.1) (under coprimality assumptions) have been obtained for k ≤ 82 in [1,Theorem 1.4] and, in completely explicit form for k ≤ 34, in [10]. The techniques of [1] do not allow for substantial strengthening of these results, however.…”

Let k be any given positive integer. We define the arithmetic function g k for any positive integer n byWe first show that g k is periodic. Subsequently, we provide a detailed local analysis of the periodic function g k , and determine its smallest period. We also obtain an asymptotic formula for log lcm 0≤i≤k {(n + i) 2 + 1}.2010 Mathematics subject classification: primary 11B25; secondary 11N13, 11A05.
“…Laishram and Shorey [23] extended this result to the case where either d ≤ 10 10 , or d has at most six prime divisors. Bennett, Bruin, Győry and Hajdu [3] solved (1) with 6 ≤ k ≤ 11 and l = 2. Hirata-Kohno, Laishram, Shorey and Tijdeman [22] completely solved (1) with 3 ≤ k < 110.…”
Abstract. In this paper we provide bounds for the size of the solutions of the Diophantine equation= y 2 , where a, b ∈ Z, a = b are parameters. We also determine all integral solutions for a, b ∈ {−4, −3, −2, −1, 4, 5, 6, 7}.
