A Ramanujan Pell Elliptic K3 Surface and Primitive Five-Cube Near Misses
K. Srinivasa Raghava
The paper constructs a trace‑16 Ramanujan–Pell family of primitive five‑cube near‑misses using quadratic form identities and Pell equations, and shows that the associated Mordell c…

Boolean Walsh Eta Units and Eisenstein Bases For Squarefree Levels
K. Srinivasa Raghava
Let be squarefree and let be its Boolean divisor cube. To each Boolean character we attach the eta-quotient \[ R_T^{(M)}(Ï)=\prod_{d\mid M}η(dÏ)^{Ï_T(d)}, \…

Hyperbolic Arcsine Kernels, Finite Fourier Filters, and Quartic Central Binomial Harmonic Sums
K. Srinivasa Raghava
Classical expansions of powers of the inverse sine contain central-binomial coefficients and finite repeated harmonic sums. We place the odd-square and ordinary-square coefficient…
