Rational normal curves in weighted projective space

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract This article aims to extend classical homological results about the rational normal curves to analogues in weighted projective spaces. Results include determinantality and nonstandard versions of quadratic generation and the Koszul property.

The weak Lefschetz property for artinian Gorenstein algebras

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract It is an extremely elusive problem to determine which standard artinian graded K$K$‐algebras satisfy the weak Lefschetz property (WLP). Codimension 2 artinian Gorenstein graded K$K$‐algebras have the WLP and it is open to what extent such result might work for codimension 3 artinian Gorenstein graded K$K$‐algebras.
