1. A large value theorem for $\zeta(s)$.

Ramachandra, K.
In this paper, we prove a slight improvement of Huxley's zero-density estimate for $\zeta(s)$ near the line ${\rm Re}(s)=\frac{3}{4}$.

2. On Riemann zeta-function and allied questions-II

Balasubramanian, R ; Ramachandra, K.
In this paper, two conjectures on the mean value of Dirichlet polynomials are given and are shown to imply good lower bound for $\int_H^{T+H}\vert\zeta(\frac{1}{2}+it)^k\vert^2\,dt$, uniform in $k$ and independent of $T$.

3. Is the binomial coefficient $2n \choose n$ square free?

Velammal, G.
In this paper, we prove the Erdös conjecture that the binomial coefficient ${2n \choose n}$ is never square free, for all $n>4$.
