Abstract:Let $\mathcal {C}$
C
be a decomposable plane curve over an algebraically closed field k of characteristic 0. That is, $\mathcal {C}$
C
is defined in k2 by an equation of the form g(x) = f(y), where g and f are polynomials of degree at least two. We use this data to construct three affine pointed Hopf algebras, A(x, a, g), A(y, b, f) and A(g, f), in the first two of which g [resp. f ] are skew primitive central elements, with the third being a factor… Show more
