Eisenstein's criterion proof
WebEisenstein's Irreducibility Criterion Theorem : Let f ( x) = a 0 + a 1 x +... + a n x n be a polynomial with integer coefficients. Suppose a prime p divides each of a 0, a 1,..., a n − … WebEisenstein died in October of tuberculosis. Our exposition of Eisenstein's proof is taken from Eisenstein's Misunderstood Geometric Proof of the Quadratic Reciprocity Theorem , by Reinhard Laubenbacher and David Pengelley, in The College Mathematics Journal, volume 25, number 1, January 1994.

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.

Webfar more generally. (Actually, Schonemann had given an irreducibility criterion in [6] that¨ is easily seen to be equivalent to Eisenstein’s criterion, and had used it to prove the irre-ducibility of Φp(x), but this had evidently been overlooked by Eisenstein; for a discussion of this see [1].) Eisenstein then went on to remark that the ... http://math.stanford.edu/~conrad/210APage/handouts/gausslemma.pdf
