Résumé : Depuis plus de deux décennies, un thème dominant marque le langage politique camerounais : le thème de l'Unité nationale. Cette idée majeure est apparue très tôt comme le point géométrique de notre discours idéologique ; comme notre mythe, au sens sorélien du terme : un mythe mobilisateur. M. Ahmadou Ahidjo apparaissait en effet comme le chantre de l'Unité nationale au Cameroun. Mais il s'agissait bien simplement d'une apparence. Car, à l'analyse, l'idée d'Unité nationale a abouti sous son règne exactement à son contraire. Elle a été minée par l'absolutisme du pouvoir qui entraîne l'intolérance politique, par l'artifice de l'"équilibre ", et suprême fléau, par l'ethnisme. Elle n'aura été qu'une arlésienne .…

Gebundene Ausgabe. Condición: Gut. Gebraucht - Gut - ungelesen,als Mängelexemplar gekennzeichnet, mit leichten Mängeln an Schnitt oder Umschlag durch Lager- oder Transportschaden -This book explores the diverse types of Schrödinger equations that appear in nonlinear systems in general, with a specific focus on nonlinear transmission networks and Bose-Einstein Condensates. In the context of nonlinear transmission networks, it employs various methods to rigorously model the phenomena of modulated matter-wave propagation in the network, leading to nonlinear Schrödinger (NLS) equations. Modeling these phenomena is largely based on the reductive perturbation method, and the derived NLS equations are then used to methodically investigate the dynamics of matter-wave solitons in the network. In the context of Bose-Einstein condensates (BECs), the book analyzes the dynamical properties of NLS equations with the external potential of different types, which govern the dynamics of modulated matter-waves in BECs with either two-body interactions or both two- and three-body interatomic interactions. It also discusses the method of investigating both the well-posedness and the ill-posedness of the boundary problem for linear and nonlinear Schrödinger equations and presents new results. Using simple examples, it then illustrates the results on the boundary problems. For both nonlinear transmission networks and Bose-Einstein condensates, the results obtained are supplemented by numerical calculations and presented as figures.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 569 pp. Englisch.…

Hardcover. Condición: new. Hardcover. This book highlights the methods to engineer dissipative and magnetic nonlinear waves propagating in nonlinear systems. In the first part of the book, the authors present methodologically mathematical models of nonlinear waves propagating in one- and two-dimensional nonlinear transmission networks without/with dissipative elements. Based on these models, the authors investigate the generation and the transmission of nonlinear modulated waves, in general, and solitary waves, in particular, in networks under consideration. In the second part of the book, the authors develop basic theoretical results for the dynamics matter-wave and magnetic-wave solitons of nonlinear systems and of BoseEinstein condensates trapped in external potentials, combined with the time-modulated nonlinearity. The models treated here are based on one-, two-, and three-component non-autonomous GrossPitaevskii equations. Based on the Heisenberg model of spinspin interactions, the authors also investigate thedynamics of magnetization in ferromagnet with or without spin-transfer torque. This research book is suitable for physicists, mathematicians, engineers, and graduate students in physics, mathematics, and network and information engineering.
