WebEisenstein's irreducibility criterion is a method for proving that a polynomial with integer coefficients is irreducible (that is, cannot be written as a product of two polynomials of … Webis linearly irreducible. In this note we develop an "Eisenstein criterion" to help answer this question. Because a linear differential operator is a special type of noncom-mutative polynomial, it is more natural to phrase the result in this more general context. The result, and indeed the proof with only slight changes

This slick proof of the irreducibility for the p-th cyclotomic polynomial was given by Eisenstein, though its irreducibility was proved by Gauss in 1799 and used by him in one of his proofs of Quadratic Reciprocity Law.
