Weak weak approximation and the Hilbert property for degree 2 del Pezzo surfaces

open access: yesProceedings of the London Mathematical Society, Volume 128, Issue 5, May 2024.
Abstract We prove that del Pezzo surfaces of degree 2 over a field k$k$ satisfy weak weak approximation if k$k$ is a number field and the Hilbert property if k$k$ is Hilbertian of characteristic zero, provided that they contain a k$k$‐rational point lying neither on any 4 of the 56 exceptional curves nor on the ramification divisor of the anticanonical

Manin triples of 3-Lie algebras induced by involutive derivations

open access: yes, 2019
For any $n$-dimensional 3-Lie algebra $A$ over a field of characteristic zero with an involutive derivation $D$, we investigate the structure of the 3-Lie algebra $B_1=A\ltimes_{ad^*} A^* $ associated with the coadjoint representation $(A^*, ad^*)$. We then discuss the structure of the dual 3-Lie algebra $B_2$ of the local cocycle 3-Lie bialgebra $(A ...

On the birational geometry of conic bundles over the projective space

open access: yesMathematische Nachrichten, Volume 297, Issue 4, Page 1208-1220, April 2024.
Abstract Let π:Z→Pn−1$\pi :Z\rightarrow \mathbb {P}^{n-1}$ be a general minimal n$n$‐fold conic bundle with a hypersurface BZ⊂Pn−1$B_Z\subset \mathbb {P}^{n-1}$ of degree d$d$ as discriminant. We prove that if d≥4n+1$d\ge 4n+1$, then −KZ$-K_Z$ is not pseudo‐effective, and that if d=4n$d = 4n$, then none of the integral multiples of −KZ$-K_{Z}$ is ...

Neo-Triple Helix Model of Innovation Ecosystems: Integrating Triple, Quadruple and Quintuple Helix Models

open access: yes, 2022
This article proposes the neo-Triple Helix model of innovation ecosystems by integrating the Triple, Quadruple and Quintuple Helix models, inspired by Lewontin’s gene, organism and environment Triple Helix metaphor.
