Labeled floor diagrams for plane curves

One says that an abelian variety A (resp. Jac C ) is geometrially isomorphi to a produt of supersingular ellipti urves.. However, the desription of the isogeny

The reduced reducible curves (two lines meeting at a point) form an irreducible family of dimension 7, and the multiplicity two structures on a line form an irreducible family

The irreducibility of 2^ g then follows from the one of My We shall find it convenient to translate our problem about plane curves into one about g^s on smooth genus ^curves, as we

The proof is based on a result on Prym varieties stated in [12], which asserts that a very generic Prym variety, of dimension greater or equal to 4, of a ramified double covering is

A complex algebraic curve is isomorphic to a curve defined by real polynomials if and only if the correspond- ing Riemann surface admits an antiholomorphic

Our main result asserts that it is determined by the base locus of the canonical divisor when the curves degenerate.. Let g: Y ~ T be a proper and smooth morphism with

We consider in this note closed curves with continuously turning tangent, with any singularities.. Regular closed
