Irreducibility of $x^{n} - a$

Biswajit Koley, A. Satyanarayana Reddy

A. Capelli gave a necessary and sufficient condition for the reducibility of $x^{n} - a$ over $\Q$. In this article, we are providing an alternate elementary proof for the same.

An irreducible class of polynomials over integers

Biswajit Koley, A. Satyanarayana Reddy

In this article, we consider polynomials of the form $f (x) = a_{0} + a_{n_{1}} x^{n_{1}} + a_{n_{2}} x^{n_{2}} + \dots + a_{n_{r}} x^{n_{r}} \in Z [x],$ where $∣ a_{0} ∣ \geq ∣ a_{n_{1}} ∣ + \dots + ∣ a_{n_{r}} ∣,$ $|a…

Irreducibility criterion for certain trinomials

Biswajit Koley, A. Satyanarayana Reddy

In this article we study the irreducibility of polynomials of the form $x^{n} + ε_{1} x^{m} + p^{k} ε_{2}$ , $p$ being a prime number. We will show that they are irreducible for $m = 1$ . We have als…

An irreducibility criterion for polynomials over integers

Biswajit Koley, A. Satyanarayana Reddy

In this article, we consider the polynomials of the form $f (x) = a_{0} + a_{1} x + a_{2} x^{2} + \dots + a_{n} x^{n} \in Z [x],$ where $∣ a_{0} ∣ = ∣ a_{1} ∣ + \dots + ∣ a_{n} ∣$ and $∣ a_{0} ∣$ is a prime. We show that…

Adjacency Algebra of Unitary Cayley Graph

A. Satyanarayana Reddy

A few properties of unitary Cayley graphs are explored using their eigenvalues. It is shown that the adjacency algebra of a unitary Cayley graph is a coherent algebra. Finally, a c…
