Cubes in products of terms from an arithmetic progression
by
Pranabesh Das, Shanta Laishram and N. Saradha
We show that there are no cubes in a product with at least
$k-(1-\epsilon)k\frac{\log\log k}{\log k},\epsilon>0,$ terms from a set of $k (\geq 2)$
successive terms in an arithmetic progression having
common difference $d$ if either $ k$ is sufficiently large or
$3^{\omega(d)}\gg k \frac{\log\log k}{\log k}.$ Here $\omega(d)$
denotes the number of distinct prime divisors of $d.$ This result
improves an earlier result of Shorey and Tijdeman.
