Quadrature rules for qualocation
2003
Qualocation is a method for the numerical treatment of boundary integral equations on smooth curves which was developed by Chandler, Sloan and Wendland (1988-2000) [1,2]. They showed that the method needs symmetric J–point–quadrature rules on [0, 1] that are exact for a maximum number of 1–periodic functions The existence of 2–point–rules of that type was proven by Chandler and Sloan. For J ∈ {3, 4} such formulas have been calculated numerically in [2]. We show that the functions Gα form a Chebyshev–system on [0, 1/2] for arbitrary indices a and thus prove the existence of such quadrature rules for any J.
Oscillatory integrals and fractal dimension
2021
Theory of singularities has been closely related with the study of oscillatory integrals. More precisely, the study of critical points is closely related to the study of asymptotic of oscillatory integrals. In our work we investigate the fractal properties of a geometrical representation of oscillatory integrals. We are motivated by a geometrical representation of Fresnel integrals by a spiral called the clothoid, and the idea to produce a classification of singularities using fractal dimension. Fresnel integrals are a well known class of oscillatory integrals. We consider oscillatory integral $$ I(\tau)=\int_{; ; \mathbb{; ; R}; ; ^n}; ; e^{; ; i\tau f(x)}; ; \phi(x) dx, $$ for large value…
Left braces and the quantum Yang-Baxter equation
2019
[EN] Braces were introduced by Rump in 2007 as a useful tool in the study of the set-theoretic solutions of the Yang¿Baxter equation. In fact, several aspects of the theory of finite left braces and their applications in the context of the Yang¿Baxter equation have been extensively investigated recently. The main aim of this paper is to introduce and study two finite brace theoretical properties associated with nilpotency, and to analyse their impact on the finite solutions of the Yang¿Baxter equation.
Breather Molecular Complexes in a Passively Mode‐Locked Fiber Laser
2021
International audience; Breathing solitons are nonlinear waves in which the energy concentrates in a localized and oscillatory fashion. Similarly to stationary solitons, breathers in dissipative systems can form stable bound states displaying molecule-like dynamics, which are frequently called breather molecules. So far, the experimental observation of optical breather molecules and the real-time detection of their dynamics are limited to diatomic molecules, that is, bound states of only two breathers. In this work, the observation of different types of breather complexes in a mode-locked fiber laser: multibreather molecules, and molecular complexes originating from the binding of two breat…
A Differentiated European Union
2020
Differentiation in the EU has substantially increased. It does not only refer to instances of (differentiation in) integration, but also (potential) disintegration. Differentiation can often be causally traced back to crises, yet it should not be equated with ‘crisis’. However, the literature has only scarcely discussed the putative link between crisis and differentiated integration. Fundamentally, demands for differentiation need to be treated as both a cause and an effect of integration. Thus, differentiation should be acknowledged as a persistent feature of European integration. The chapter discusses the development of differentiation in European integration and reflects upon the scholar…

L’autonomia di spesa delle Regioni fra Stato ed Unione europea dalla l. cost. 3/2001 alle condizionalità europee sulla ripresa e la resilienza
2021
L'articolo ricostruisce la tendenza all’accentramento nel governo delle finanze pubbliche e l’eccessiva distanza fra testo costituzionale e diritto costituzionale vivente per analizzare l'attuazione del Recovery Plan (PNRR) rilevando un ulteriore tendenza all’accentramento del governo della spesa. Si indagano dunque le ragioni della compressione dell’autonomia finanziaria di spesa per effetto del principio di indifferenza e del “doppio intreccio federale”. Si mira a inquadrare il tema alla luce della leale collaborazione e dellala resilienza istituzionale per accorciare la “distanza” fra testo costituzionale ed attuazione costituzionale in tema di autonomia di spesa delle Regioni. Si prospe…
