On Weierstra{\ss} semigroups at one and two points and their corresponding Poincar\'e series
The aim of this paper is to introduce and investigate the Poincar\'e series
associated with the Weierstra{\ss} semigroup of one and two rational points at
a (not necessarily irreducible) non-singular projective algebraic curve defined
over a finite field, as well as to describe their functional equations in the
case of an affine complete intersection.Comment: Beginning of Section 3 and Subsection 3.1 were modifie
On certain remarkable curves of genus five
We characterize the genus five curves having exactly 24 Weierstass points, and in particular we show that they are unramified double covering of the Fermat's quartic
Letters of Sophie Germain preserved in Florence
Published here, and discussed, are some manuscripts and a letter of Sophie Germain concerning her work on Fermat's last theorem. These autographs, held at the Bibliothèque Nationale of Paris, at the Moreniana Library of Florence and at the University Library of Göttingen, contribute to a substantial revaluation of her work on this subject
Abel's surviving manuscripts including the one recently found in London
We list and locate all N.H. Abel's surviving manuscripts and trace a short history of them. We also present, with some comments, a manuscript that was discovered in London very recently. In the note we give a brief account of what happened to the manuscript that Abel sent to A.L. Crelle ad we report the very recent discovery of the memoirs that Crelle published under the title "Remarques sur quelque propriete generales d'une certaine sorte de functions trascendentes"
Scrollar invariants and resolutions of certain d-gonal curves
Embeddings of d-gonal curves are studied and also resolution of their ideal
On the Correspondence of Sophie Germain
The aim of this paper is to give a thorough account of the presently known correspondence of Sophie Germain, as well as the history of its discovery and editing. In particular, we will focus on the correspondence with Gauss and Guglielmo Libri
The rationality of certain moduli spaces associated to half-canonical extremal curves
AbstractWe prove the existence of a coarse, irreducible moduli space Cm−1g (resp. Cm−1g,1) for (resp. pointed) subcanonical extremal curves of level m−1 and genus g in PCr. When g=3r, r≥4, r≠5, odd (resp. even) we show that C23r (resp. C23r,1) is rational
