Abstract:1. Introduction. Let b, d, , n and y be positive integers such that gcd(n, d) = 1 and > 2 is a prime number. Let k ≥ 2, t ≥ 2 and r ∈ {0, 1} be integers satisfying t = k − r. Thus k ≥ 2 if r = 0 and k ≥ 3 if r = 1. Let d 1 < . . . < d t be integers in the interval [0, k). We write

“…Then we see from [17] and [12,Theorem 4] that the left-hand side of (2.11) is divisible by a prime exceeding k. Furthermore, by [12, Theorem 4 0 ], the left-hand side of (2.11) is divisible by at least two distinct primes exceeding k whenever t ¼ k 5 4. Thus we see from (2.11), (2.6) and (2.7) that n þ ðk À 1Þd 5 q Analogously, we partition the set of a i 's in the following way.…”
Abstract. It is proved that a product of four or more terms of positive integers in arithmetic progression with common difference a prime power is never a square. More general results are given which completely solve (1.1) with gcdðn; d Þ ¼ 1; k 5 3 and 1 < d 4 104.

“…Obláth [25] obtained a similar statement for k = 5. Saradha and Shorey [30] proved that (1) has no solutions with k ≥ 4, provided that d is a power of a prime number. Laishram and Shorey [23] extended this result to the case where either d ≤ 10 10 , or d has at most six prime divisors.…”
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}.
