Syzygies of Jacobian ideals and weighted homogeneous singularities
Let $V$ be a projective hypersurface having only isolated weighted homogeneous singularities. We show that the Koszul syzygies among the partial derivatives of an equation for $V$ are exactly the syzygies vanishing on the singular locus subscheme of $V$. A positive answer to a question raised by Morihiko Saito and the first author is also given in this setting. We explain how our result can be used to improve the listing of Jacobian syzygies of a given degree by the computer algebra systems such as Singular, CoCoA or Macauley2.

Que maten al papagayo acusador
Revue interdisciplinaire d'études hispaniques médiévales et modernes 48 | Juin 2024 Animaux et violence (Époques médiévale et moderne) / Porosités et circulations dans les espaces d'enfermement (XVI e-XVII e siècles), 2024
En los cuentos medievales de origen oriental figura el papagayo como un ave con capacidad de hablar como los humanos. Esta característica lo convierte en protagonista de algunos relatos porque le permite actuar como espía para el marido celoso pero, en última instancia, esa será la causa de su muerte ya que el ave caerá en la trampa de la astuta esposa espiada. En esta intervención se trazará un breve recorrido desde los cuentos del Calila e Dimna y el Sendebar castellanos hasta sus derivaciones posteriores y se analizarán las causas de la sustitución del colorido papagayo por la más vulgar urraca en estos textos más tardíos, ya plenamente peninsulares. Palabras clave: papagayo, urraca, Calila e Dimna, Sendebar, Exemplario contra los engaños y peligros del mundo.
