Characterization of separable polynomials over a commutative ring
Throughout this paper B will mean a commutative ring with an identity element, and all ring extensions of B will be assumed com- mutative with identity element coinciding with the identity element of B.Moreover, X will be an indeterminate, and by B[X] denote the ring of polynomials in X with …
