Diophantine approximation with sums of two squares

Stephan Baier, Habibur Rahaman

For any given positive definite binary quadratic form $Q$ with integer coefficients, we establish two results on Diophantine approximation with integers represented by $Q$ . Firstly…

Diophantine Approximation with Piatetski-Shapiro Primes

Stephan Baier, Habibur Rahaman

We prove that for every irrational number $I^\pm$ , real number $I^^{2}$ , real number $c$ satisfying $1 < c < 9/8$ and positive real number $I^¸$ satisfying $I^¸ < (9/ c - 8) /10$ , there exist infinit…

Primes and polygonal numbers

Soumya Bhattacharya, Habibur Rahaman

A linear combination $a T_{r} (m) + b T_{s} (n)$ of an \mbox{ $r$ -gonal} number $T_{r} (m)$ and an $s$ -gonal number $T_{s} (n)$ with mutually coprime positive integer coefficients $a$ and $b$ produ…
