An Arithmetic Sum Associated with the Classical Theta Function

Bruce C. Berndt, Raghavendra N. Bhat, Jeffrey L. Meyer +2

The sum $S (h, k) := \sum_{j = 1}^{k - 1} (- 1)^{j + 1 + [hj / k]}$ appears in the modular transformation formulae of the classical theta function $ϑ_{3} (z)$ . The double sum $S(k) := \sum_{h…

Twisted aughts of alternating involutions

Raghavendra N. Bhat, Cristian Cobeli, Shuta Iwai +2

Let $M (n)$ be the subgroup of $G L (n, Z)$ generated by the particular involutions that are identical to the identity, except for a single line where $- 1$ and $+ 1$ …

Filtered rays over iterated absolute differences on layers of integers

Raghavendra N. Bhat, Cristian Cobeli, Alexandru Zaharescu

The dynamical system generated by the iterated calculation of the high order gaps between neighboring terms of a sequence of natural numbers is remarkable and only incidentally cha…
