Note on a paper "An Extension of a Theorem of Euler" by Hirata-Kohno et al
In this paper we extend a result of Hirata-Kohno, Laishram, Shorey and
Tijdeman on the Diophantine equation where
and are positive integers such that $\gcd(n,d)=1.
On the Diophantine equation
In this paper we consider the Diophantine equation where
are integer unknowns with and are odd primes and
We prove that there are only finitely many solutions
for which is not a sum of two consecutive squares. We also
study the above equation with fixed and with fixed $q.
Composite Rational Functions and Arithmetic Progressions
In this paper we deal with composite rational functions having zeros and
poles forming consecutive elements of an arithmetic progression. We also
correct a result published earlier related to composite rational functions
having a fixed number of zeros and poles
On products of disjoint blocks of arithmetic progressions and related equations
In this paper we deal with Diophantine equations involving products of
consecutive integers, inspired by a question of Erd\H{o}s and Graham.Comment: 10 page
Trinomials ax8+bx+c with Galois groups of order 1344
Bruin and Elkies ([7]) obtained the curve of genus 2 parametrizing trinomials ax8 + bx + c whose Galois group is contained in G1344 = (ℤ/2)3 ⋊ G168. They found some rational points of small height and computed the associated trinomials. They conjecture that the only ℚ-rational points of the hyperelliptic curve
Y2 = 2X6 + 28X5 + 196X4 + 784X3 + 1715X2 + 2058X + 2401
are given by (X, Y ) = (0, ± 49), (-1, ± 38), (-3, ± 32), and (-7, ± 196). In this paper we prove that the above points are the only S-integral points with S={2,3,5,7,11,13,17,19}
