An Extension to Fermat's Factorisation and a simple primality test
Satyabrata Adhikari, Abhijit Sen
An extension to the factorisation principle as suggested by Fermat is presented.We start from a symmetry of natural numbers and obtain the factorisation principle therefrom.Later i…

A Computational Algorithm for /pi(N)
Abhijit Sen, Satyabrata Adhikari
An algorithm for computing /pi(N) is presented.It is shown that using a symmetry of natural numbers we can easily compute /pi(N).This method relies on the fact that counting the nu…
