A basic characteristic of twin primes and its generalization
• Mathematics
• 2004
The sum of powers of positive divisors of an integer, expressed in terms of the floor function, provides the basis for another characterization of twin primes in particular, and of prime k-tuplesâ€¦
Note on Perfect Numbers and their Existence
This paper will address the interesting results on perfect numbers. As we know that, perfect number ends with 6 or 8 and perfect numbers had some special relation with primes. Here one can understandâ€¦
Generating Tuples of Integers Modulo n

A VARIATION ON PERFECT NUMBERS
For k2 N we deflne a new divisor function sk called the k th prime symmetric function. By analogy with the sum of divisors function ae, we use the functions sk to consider variations on perfectâ€¦
A Note on Boolean Lattices and Farey Sequences III
We establish monotone bijections between subsequences of the Farey sequences and the halfsequences of Farey subsequences associated with elements of the Boolean lattices.
