Scrollar invariants and resolutions of certaind-gonal curves

- A. Centina, A. Gimigliano
- Mathematics
- 1995

In this note we compute the scrollar invariants of certaind-gonal curves (e.g. Castelnuovo curves and bielliptic curves) by using appropriate plane models. Ford=4 andg(C)≥10, we show that those… Expand

Weierstrass points and their impact in the study of algebraic curves: a historical account from the “Lückensatz” to the 1970s

- A. Centina
- Mathematics
- 11 March 2008

In this note we give a historical account of the origin and the development of the concept of Weierstrass point. We also explain how Weierstrass points have contributed to the study of compact… Expand

Poncelet’s porism: a long story of renewed discoveries, I

- A. Centina
- Mathematics
- 2016

In 1813, J.-V. Poncelet discovered that if there exists a polygon of n-sides, which is inscribed in a given conic and circumscribed about another conic, then infinitely many such polygons exist. This… Expand

Projective surfaces with bi-elliptic hyperplane sections

- A. Centina, A. Gimigliano
- Mathematics
- 1 December 1991

We study projective surfaces X which have a bi-elliptic curve (i.e. 2∶1 covering of an elliptic curve) among their hyperplane sections . We give a complete characterization of those surfaces when… Expand
