New Formulas for Semi-Primes. Testing, Counting and Identification of the and next Semi-Primes
Issam Kaddoura, Samih Abdul-Nabi, Khadija Al-Akhrass
In this paper we give a new semiprimality test and we construct a new formula for , the function that counts the number of semiprimes not exceeding a given number .…
Construction of semi-free S3 actions on homotopy sphere with untwisted fixed point set
I. H. Kaddoura
William Browder in his paper "Surgery and the theory of differentiable transformation groups" developed surgery techniques to study semi-free actions of S1 on homotopy spheres, und…
De-suspension of free S3 - actions on Homotopy Spheres
Issam Kaddoura
In the paper of Montgomery, D. and Yang, C.T. [5], they discuss the de-suspension of smooth free actions of S1 on (2n+1)-dimensional homotopy spheres. In this paper we discuss the…
An algorithm for constructing doubly stochastic matrices for the inverse eigenvalue problem
Bassam Mourad, Hassan Abbas, Ayman Mourad +2
In this note, we present an algorithm that yields many new methods for constructing doubly stochastic and symmetric doubly stochastic matrices for the inverse eigenvalue problem. I…
