Eisenstein and the quintic equation / S.J. Patterson.
Abstract:
'In a footnote to a short early paper (1844), G. Eisenstein gave an ànalytic solution' of the general quintic equation. We discuss this remark in relation to the well-known work of Hermite (1858) and Kronecker (1861). We also discuss Eisenstein's solution from the point of view of Riemannian function theory.'
