As is well-known, the celebrated Riemann Hypothesis (RH) is the prediction that all the non-trivial zeros of the zeta function ζ(s) lie on a vertical line in the complex s-plane at Re(s) = 1/2. Very many efforts to prove this statement have been directed to investigating the analytic properties of the zeta function, however all these efforts have n...

In this paper, drawing on the methods I previously developed for the proof of RH, I offer two different proofs of the Generalized Riemann Hypothesis. The first is based on the Summatory Liouville function and the second [in the Appendix] on the Mertens function involving the Mobius coefficients. In my work 2018 [1], I briefly made the point that my...

Breast cancer is a disease which occurs when the cells in the breast grow out of control due to the changes in the genes called mutations. These abnormal cells get accumulated and eventually form a tumor or can be felt as a lump. The main factors causing breast cancer are advancing age and family history.
