Some order dualities in logic, games and choices [PDF]

open access: yes
We first present the concept of duality appearing in order theory, i.e. the notions of dual isomorphism and of Galois connection. Then, we describe two fundamental dualities, the duality extension/intention associated with a binary relation between two ...

Lectures on differential Galois theory

open access: yes, 1994
Differential Galois theory studies solutions of differential equations over a differential base field. In much the same way that ordinary Galois theory is the theory of field extensions generated by solutions of (one variable) polynomial equations ...

Bridging 4D QFTs and 2D VOAs via 3D high-temperature EFTs

open access: yesJournal of High Energy Physics
The high-temperature limit of the superconformal index, especially on higher sheets, often captures useful universal information about a theory. In 4d N = 2 $$ \mathcal{N}=2 $$ superconformal field theories with fractional r-charges, there exists a ...

A Meta-Logical Framework for the Equivalence of Syntactic and Semantic Theories

open access: yesPhilosophies
This paper introduces a meta-logical framework—based on the theory of institutions (a categorical version of abstract model theory)—to be used as a tool for the formalization of the two main views regarding the structure of scientific theories, namely ...

Looking for the G 2 Higgs branch of 4D rank 1 SCFTs

open access: yesJournal of High Energy Physics
The Schur index of the Higgs branch of 4-dimensional N $$ \mathcal{N} $$ = 2 SCFTs is related to the spectrum of non-unitary 2-dimensional CFTs. The rank 1 case has been shown to lead to the non-unitary CFTs with Deligne-Cvitanovic (DC) exceptional ...

Inverse Galois theory

open access: yes, 2018
This second edition addresses the question of which finite groups occur as Galois groups over a given field. In particular, this includes the question of the structure and the representations of the absolute Galois group of K, as well as its finite ...
