All opinions are not equal: Toward a consensual approach to the development of drug policy
Abstract Drug policy has been subjected to much scrutiny from different stakeholder groups who present sometimes very different opinions on solutions to address a problem. Reconciling such differences, that are underpinned by both anecdotal and empirical evidence, is a priority yet to be fully achieved.

Soft factorization in QED from 2D Kac-Moody symmetry
The soft factorization theorem for 4D abelian gauge theory states that the S $$ \mathcal{S} $$-matrix factorizes into soft and hard parts, with the universal soft part containing all soft and collinear poles.

Bethe Vectors of Quantum Integrable Models with GL(3) Trigonometric R-Matrix
We study quantum integrable models with GL(3) trigonometric $R$-matrix and solvable by the nested algebraic Bethe ansatz.Using the presentation of the universal Bethe vectors in terms of projections of products of the currents of the quantum affine ...

(Chiral) Virasoro invariance of the tree-level MHV graviton scattering amplitudes
In this paper we continue our study of the tree level MHV graviton scattering amplitudes from the point of view of celestial holography. In arXiv:2008.04330 we showed that the celestial OPE of two gravitons in the MHV sector can be written as a linear ...

Current Algebraic Structures over Manifolds: Poisson Algebras, q-Deformations and Quantization [PDF]
Poisson algebraic structures on current manifolds (of maps from a finite dimensional Riemannian manifold into a 2-dimensional manifold) are investigated in terms of symplectic geometry. It is shown that there is a one to one correspondence between such current manifolds and Poisson current algebras with three generators. A geometric meaning is given to

We present a global, synthetic and updated vision of the contributions made by the anthropological theory of the didactic to the problem of teaching elementary algebra. We start by summarising the first results obtained by Yves Chevallard in the 80s that

Bondi-Metzner-Sachs (BMS) symmetries, or equivalently Conformal Carroll symmetries, are intrinsically associated to null manifolds and in two dimensions can be obtained as an Inönü-Wigner contraction of the two-dimensional (2d) relativistic conformal ...

A current algebra approach to the equilibrium classical statistical mechanics and its applications
The non-relativistic current algebra approach is analyzed subject to its application to studying the distribution functions of many-particle systems at the temperature equilibrium and their stability properties.

Diffeomorphisms as quadratic charges in 4d BF theory and related TQFTs
We present a Sugawara-type construction for boundary charges in 4d BF theory and in a general family of related TQFTs. Starting from the underlying current Lie algebra of boundary symmetries, this gives rise to well-defined quadratic charges forming an ...

OFF-CRITICAL CURRENT ALGEBRAS [PDF]
We discuss the infinite-dimensional algebras appearing in integrable perturbations of conformally invariant theories, with special emphasis on the structure of the consequent non-Abelian infinite-dimensional algebra generalizing W∞ to the case of a non-Abelian group.
