Log-concavity And The Multiplicative Properties of Restricted Partition Functions

Arindam Roy

The partition function $p (n)$ and many of its related restricted partition functions have recently been shown independently to satisfy log-concavity: $p (n)^{2} \geq p (n - 1) p (n + 1)$ for…

Non-zero values of a family of approximations of a class of $L$ -functions

Arindam Roy, Kevin You

Consider the approximation $Z ~_{N} (s) = \sum_{n = 1}^{N} n^{- s} + I ¨ (s) \sum_{n = 1}^{N} n^{1 - s}$ of the Riemann zeta function $I^¶ (s)$ , where $I ¨ (s)$ is the ratio of the gamma functio…

End behavior of Ramanujan's taxicab numbers

Brennan Benfield, Oliver Lippard, Arindam Roy

Generalized taxicab numbers are the smallest positive integers that are the sum of exactly $j$ , positive $k$ -th powers in exactly $m$ distinct ways. This paper is considers for whi…
