Histoire de l'École Nationale Vétérinaire de Toulouse dans ses relations avec l'urbanisme toulousain

Author(s) : Abdesselam, Marion
Description : La première école vétérinaire toulousaine établie à Matabiau dès 1825 selon les plans de Jean-Pierre Laffon est un exemple remarquable d’ édifice public néoclassique approuvé par le Conseil des bâtiments Civils, dans le respect de la structure largement employée du collège jésuite de la Contre-Réfor...

A Complete Renormalization Group Trajectory Between Two Fixed Points

Description : We give a rigorous nonperturbative construction of a massless discrete trajectory for Wilson's exact renormalization group. The model is a three dimensional Euclidean field theory with a modified free propagator. The trajectory realizes the mean field to critical crossover from the ultraviolet Gau...

The Jacobian Conjecture as a Problem of Perturbative Quantum Field Theory

Author(s) : Abdesselam, A.
Description : The Jacobian conjecture is an old unsolved problem in mathematics, which has been unsuccessfully attacked from many different angles. We add here another point of view pertaining to the so called formal inverse approach, that of perturbative quantum field theory. , Comment: 22 pages, 13 diagrams

A Physicist's Proof of the Lagrange-Good Multivariable Inversion Formula

Author(s) : Abdesselam, A.
Description : We provide yet another proof of the classical Lagrange-Good multivariable inversion formula using techniques of quantum field theory. , Comment: 9 pages, 3 diagrams

Feynman Diagrams in Algebraic Combinatorics

Description : We show, in great detail, how the perturbative tools of quantum field theory allow one to rigorously obtain: a ``categorified'' Faa di Bruno type formula for multiple composition, an explicit formula for reversion and a proof of Lagrange-Good inversion, all in the setting of multivariable power se...

Grassmann-Berezin Calculus and Theorems of the Matrix-Tree Type

Description : We prove two generalizations of the matrix-tree theorem. The first one, a result essentially due to Moon for which we provide a new proof, extends the ``all minors'' matrix-tree theorem to the ``massive'' case where no condition on row or column sums is imposed. The second generalization, which is...

A Computational Solution to a Question by Beauville on the Invariants of the Binary Quintic

Description : We obtain an alternate proof of an injectivity result by Beauville for a map from the moduli space of quartic del Pezzo surfaces to the set of conjugacy classes of certain subgroups of the Cremona group. This amounts to showing that a projective configuration of five distinct unordered points on t...

Atypical Representations of $U_{q}(sl(N))$ at Roots of Unity

Author(s) : Abdesselam, Boucif
Description : We show how to adapt the Gelfand-Zetlin basis for describing the atypical representation of ${\cal U}_{\displaystyle{q}}(sl(N))$ when $q$ is root of unity. The explicit construction of atypical representation is presented in details for $N=3$. , Comment: 18 pages, Tex-file and 2 figures. Uuencoded, ...

The Twisted Heisenberg Algebra ${\cal U}_{h,w}({\cal H}(4))$

Author(s) : Abdesselam, Boucif
Description : A two parametric deformation of the enveloping Heisenberg algebra ${\cal H}(4)$ which appear as a combination of the standard and a nonstandard quantization given by Ballesteros and Herranz is defined and proved to be Ribbon Hopf algebra. The universal ${\cal R}$-matrix and its associated quantum ...
