Instanton Counting, Quantum Geometry and Algebra
2020
The aim of this memoir for "Habilitation \`a Diriger des Recherches" is to present quantum geometric and algebraic aspects of supersymmetric gauge theory, which emerge from non-perturbative nature of the vacuum structure induced by instantons. We start with a brief summary of the equivariant localization of the instanton moduli space, and show how to obtain the instanton partition function and its generalization to quiver gauge theory and supergroup gauge theory in three ways: the equivariant index formula, the contour integral formula, and the combinatorial formula. We then explore the geometric description of $\mathcal{N} = 2$ gauge theory based on Seiberg-Witten geometry together with it…
La rationalité simonienne : interprétations et enjeux épistémologiques
1999
Since economics focuses on individual behaviour and implicitly adopt a methodological individualism, an individual rationality hypothesis must be laid down. Beyond the usual substantive rationality hypothesis, others forms of individual rationality can be found in economics theory. They are often related to the Simon's bounded rationality hypothesis. In the economics literature the meanings of the bounded rationality hypothesis are obviously diverse and sometimes based on a partial or superficial readings of Simon's writings. Moreover, each one of these meanings is implicitly closely linked with a particular methodological and epistemological position. Based on careful readings of Simon's w…

Addressing and control of optical nanosources by integrated or fibered plasmonics
2015
Surface plasmon polariton (SPP) can confine light on subwavelength dimensions. Since they are not diffraction limited, they are of great interest for addressing and controlling optical nanosources. For example, a metal nanowire defines 1D plasmonic waveguide with a great potential for either addressing or coupling quantum emitters. Therefore, SPP opens great opportunities for integrated optical applications. However, SPP suffer from ohmic losses that jeopardize the applications of plasmonic components. In this context, we study the possibilities provided by an hybrid plasmonic-photonicstructure to couple efficiently an emitter to a fiber mode. Such a structure paves the way for fibered sing…

À la recherche du lien perdu entre caractéristiques des dirigeants et performance de la firme : gouvernance et latitude managériale
2008
Upper Echelons Theory and financial governance theory both postulate that CEOs have a determining influence on the performance with, however, a very significant difference concerning the influence of managerial discretion. For the first one, managerial discretion has a potentially positive influence on performance by enabling the managers' cognitive capacities to affect it, for the second one, a negative influence, insofar as it can lead to decisions conflicting with shareholders' interests. The objective of this article is, on the one hand, to compare the contents and the role of the managerial discretion concept within these two theoretical frameworks, on the other hand, to propose, in th…
Le siège de l'arbitrage international
2021
In international matters, the arbitral tribunal has no choice but to settle in the territory of a State in order to render its award. The choice of this "host State" would then determine the seat of international arbitration. But what choice do we make? How? By whom ? What to do in case of uncertainty of this choice? What effects will this determination then have in creating the tribunal, in rendering and enforcing its award, or in choosing the applicable laws? There is no single answer to these simple questions. Indeed, international arbitration law attaches varying importance to the notion of seat, in the sense that it will depend primarily on one's vision of the place and source of arbit…
La construction de métaphores scientifiques dans les discours publics de médecins germanophones au XIXème siècle : contribution à une approche diachr…
2016
National audience; Cette proposition de communication vise à interroger la notion de métaphore à travers un double prisme. D’une part, non pas comme ‘figure’, ainsi qu’elle l’est dans une longue tradition à l’intersection entre rhétorique et stylistique, mais comme schéma de pensée à la suite de la théorie des métaphores conceptuelles initiée dans les années 1980 par Lakoff/Johnson et largement discutée, critiquée et enrichie depuis lors. D’autre part, à partir d’un corpus de textes pouvant être qualifiés d’hybrides puisque constitués de discours publics de médecins abordant des questions scientifiques, mais aussi plus globalement sociétales voire philosophiques. Ces textes, qui ne sont pas…
Effet de moiré et dérobades diégétiques chez Vautrin
2015
Questo articolo intende esaminare l’importanza dell’abbigliamento e dei vestiti in Balzac, in particolare le diverse tenute del personaggio Vautrin fin dalla sua prima apparizione nel “Père Goriot” (1834), passando per le “Illusions perdues” (1835-1843) e fino a “Splendeurs et misères des courtisanes” (1838-1847); frattanto, Vautrin ha preso anche a calcare le scene in una pièce omonima rappresentata nel 1840. Attraverso uno studio che tiene conto dell’analisi della descrizione e delle sue implicazioni psicoanalitiche, si mostra come l’uso del vestito serva da tramite alle “dé-robades” della diegesi. This article aims to examine the importance of clothing in Balzac, especially the different…
