The Higgs mechanism — Hasse diagrams for symplectic singularities by Antoine Bourget, Santiago Cabrera, Julius F. Grimminger, Amihay Hanany, Marcus Sperling, Anton Zajac, Zhenghao Zhong

“…Most of the Hasse diagrams we obtain extend beyond the cases of nilpotent orbit closures known in the mathematics literature. The geometric analysis developed in this paper is applied to Higgs branches of several Lagrangian gauge theories, Argyres-Douglas theories, five dimensional SQCD theories at the conformal fixed point, and six dimensional SCFTs.…”

Delay differential equations via the matrix lambert w function and bifurcation analysis: application to machine tool chatter by Sun Yi, Patrick W. Nelson, A. Galip Ulsoy

“…The bifurcation method combined with Sturmsequences provides an algorithm for determining the stability ofDDEs without restrictive geometric analysis. With this approach, onecan obtain the critical values of delay, which determine thestability of a system and hence the preferred operating spindlespeed without chatter. …”

Geophysical Contribution in the Characterization of Deep Water Tables Geometry (Sidi Bouzid, Central Tunisia) by D. Khazri, H. Gabtni

“…The obtained results allowed refining the geostructural schema by highlighting the individualization of the NE-SW underground convexity of Ouled Asker and the anticline of axis Es Souda-Hmaeima and Ezaouia on either sides of two hydrogeological thresholds. The geometrical analysis determined the spatial extension of Ouled Asker and Oued El Hajel subbasins. …”

Considerations on the choice of experimental parameters in residual stress measurements by hole-drilling and ESPI by C. Barile, C. Casavola, G. Pappalettera, C. Pappalettere

“…The accuracy of the measurement, however, is influenced by the proper choice of several parameters: geometrical, analysis and experimental. In this paper, in particular, the effects of some of those parameters are investigated: misknowledgment in illumination and detection angles, the influence of the relative angle between the sensitivity vector of the system and the principal stress directions, the extension of the area of analysis and the adopted drilling rotation speed. …”

Sur les origines du concept de méthode à l’âge classique : La Ramée, Bacon et Descartes by Philippe Hamou

“…Descartes, even though he may be considered as the inventor of the modern acceptation of method as an ars inveniendi, modelled on geometrical analysis, still retained the old pedagogical connotation – it is quite clear that, for him, acquiring new knowledge methodically was the result of some sort of self-education rather than the application of formal rules. …”
