In this paper,we determine the Sombor index and some other vertex-degree-based topological indices for the nil-clean graphs of Z_(n),the ring of integers modulo n.
RSA[1],a cryptographic system essential for securing network communications,relies on the difficulty of factorizing an integer into two primes(factorizing an integer N=P×Q,where P and Q are prime numbers).In theory,q...
This paper attempts to form a bridge between a sum of the divisors function and the gamma function, proposing a novel approach that could have significant implications for classical problems in number theory, specific...
We consider Shor’s quantum factoring algorithm in the setting of noisy quantum gates.Under a generic model of random noise for(controlled)rotation gates,we prove that the algorithm does not factor integers of the for...
An elementary formula to know the number of primes in the interval (x, 2x) close to the exact figure for a fixed x is given here. A new elementary equation is derived (a relation between prime numbers and composite nu...
The application of the Euclidean division theorem for the positive integers allowed us to establish a set which contains all the prime numbers and this set we called it set of supposedly prime numbers and we noted it ...

In block ciphers,the nonlinear components,also known as substitution boxes(S-boxes),are used with the purpose to induce confusion in cryptosystems.For the last decade,most of the work on designing S-boxes over the poi...

We generalize the congruences of Friedmann-Tamarkine (1909), Lehmer (1938), and Ernvall-Metsänkyla (1991) on the sums of powers of integers weighted by powers of the Fermat quotients to the next Fermat quotient power,...
In our earlier paper,we generalize the one-parameter(c)family of inhomoge-neous first-order differential operator representations of the orthogonal Lie algebras arising from conformal transformations to those of ortho...
