The global gauge group structure of F-theory compactification with U(1)s [PDF]

open access: yesJournal of High Energy Physics, 2018
We show that F-theory compactifications with abelian gauge factors generally exhibit a non-trivial global gauge group structure. The geometric origin of this structure lies with the Shioda map of the Mordell-Weil generators.

Wilson loops, geometric operators and fermions in 3d group field theory

open access: yesOpen Physics, 2011
Group field theories whose Feynman diagrams describe 3d gravity with a varying configuration of Wilson loop observables and 3d gravity with volume observables at each vertex are defined.

Geometric and algebraic approaches to quantum theory

open access: yesNuclear Physics B, 2021
We show how to formulate physical theory taking as a starting point the set of states (geometric approach). We discuss the relation of this formulation to the conventional approach to classical and quantum mechanics and the theory of complex systems. The

The Problems of Dimension Four, and Some Ramifications

open access: yesMathematics, 2023
In this short note, I present a very quick review of the peculiarities of dimension four in geometric topology. I consider, in particular, the role of geometric simple connectivity (which means handle decomposition without handles of index one) for both ...

3D geometric moment invariants from the point of view of the classical invariant theory

open access: yesМатематичні Студії, 2023
The aim of this paper is to clear up the problem of the connection between the 3D geometric moments invariants and the invariant theory, considering a problem of describing of the 3D geometric moments invariants as a problem of the classical invariant ...

Generalized Permutants and Graph GENEOs

open access: yesMachine Learning and Knowledge Extraction, 2023
This paper is part of a line of research devoted to developing a compositional and geometric theory of Group Equivariant Non-Expansive Operators (GENEOs) for Geometric Deep Learning. It has two objectives. The first objective is to generalize the notions

Hamiltonian actions of unipotent groups on compact K\"ahler manifolds [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2018
We study meromorphic actions of unipotent complex Lie groups on compact K\"ahler manifolds using moment map techniques. We introduce natural stability conditions and show that sets of semistable points are Zariski-open and admit geometric quotients that ...

2-Group symmetries and M-theory

open access: yesSciPost Physics, 2022
Quantum Field Theories engineered in M-theory can have 2-group symmetries, mixing 0-form and 1-form symmetry backgrounds in non-trivial ways. In this paper we develop methods for determining the 2-group structure from the boundary geometry of the M ...

Circuit complexity for Carrollian Conformal (BMS) field theories

open access: yesJournal of High Energy Physics, 2023
We systematically explore the construction of Nielsen’s circuit complexity to a non-Lorentzian field theory keeping in mind its connection with flat holography.
