Discrete Breathers in Nonlinear Lattices: A Review and Recent Results,sults on the efficient computation of breathers in multi-dimensional lattices using homoclinic orbits. This allows us to make a much more detailed study and classification of discrete breathers than had previously been possible, as well as accurately follow their existence and stability properties a作者: dainty 時間: 2025-3-22 01:56 作者: Gullible 時間: 2025-3-22 04:59 作者: 鍍金 時間: 2025-3-22 12:20 作者: ANN 時間: 2025-3-22 15:10 作者: ANN 時間: 2025-3-22 20:09
Motions of a Black Hole near the Center of a Galaxy,a massive particle, we suggested that similar physical effects might cause a massive particle near the center to oscillate with larger amplitudes than indicated by simple Brownian motion arguments. Results from recent experiments will be reported to clarify some of the issues raised by a massive particle (a black hole) near the center.作者: obeisance 時間: 2025-3-22 21:56 作者: 細胞膜 時間: 2025-3-23 05:00 作者: endoscopy 時間: 2025-3-23 09:00 作者: 動機 時間: 2025-3-23 19:02 作者: 追逐 時間: 2025-3-23 23:11 作者: Arresting 時間: 2025-3-24 02:49

Chaos or Order in Double Barred Galaxies?,lign generates a closed curve, which we call a loop. Loops allow us to verify consistency of the potential.

Jeans Solutions for Triaxial Galaxies,ystems, there are three equations, but these are not very helpful, as they contain six independent moments. By assuming that the potential is triaxial and of separable St?ckel form, the mixed moments vanish in confocal ellipsoidal coordinates.

Disk-Crossing Orbits,esent evidence that this simplifying assumption is not critical. We find that the presence of the disk causes many more resonances than have been found in similar smooth potentials. Those resonances grow at relatively modest values of energy, overlap, and give rise to many stochastic orbits. A signi作者: SHRIK 時間: 2025-3-29 14:55
