Christian Rügerunding these is the way by which the vorticity initially is created in the flow. One explanation lies in the nonlinear occurrence of vortex sheets admitted as a solution to the Euler equations. The sheets may arise from the build up and breaking of simple shear waves, and seems associated with singu使混合 发表于 2025-3-25 11:28:58

Christian Rügereography of the world. Therefore, Cosmology is one of the oldest human concern. On the other hand, despite the fact that scientific approaches to the question has existed from time to time, the developpment of “Physical Cosmology” is very young. So young that its scientific status is sometime quest试验 发表于 2025-3-26 05:22:17

Christian Rügerher Members of the Organizing Committees are to be congratulated for having given us a taste of this excitement in Trieste, by inviting the leaders of the subject to the meeting they have organized. The excitement has corne from the new observations of the three-dimensional structure of the universe刺耳的声音 发表于 2025-3-26 16:09:16

. Both the compressible and the incompressible (Boussinesq) case are treated..We consider first a non rotating configuration. It is well known that the solutions of the linear problem are degenerate, due to the spherical symmetry, and that their angular behaviour is in the form of spherical harmonic
