15 صفحه اولNowhere Precipitousness of the Non - Stationary Ideal Over
We prove that if λ is a strong limit singular cardinal and κ a regular uncountable cardinal < λ, then NSκλ, the non-stationary ideal over Pκλ, is nowhere precipitous. We also show that under the same hypothesis every stationary subset of Pκλ can be partitioned into λ disjoint stationary sets.
متن کاملRouth’s procedure for non-Abelian symmetry groups
We extend Routh’s reduction procedure to an arbitrary Lagrangian system (that is, one whose Lagrangian is not necessarily the difference of kinetic and potential energies) with a symmetry group which is not necessarily Abelian. To do so we analyse the restriction of the Euler-Lagrange field to a level set of momentum in velocity phase space. We present a new method of analysis based on the use ...
متن کاملThe stationary behavior of ideal TCP congestionavoidanceTeunis
This note derives the stationary behavior of idealized TCP congestion avoidance. More speciically, it derives the stationary distribution of the congestion window size if loss of packets are independent events with equal probability. The mathematical derivation uses a uid ow, continuous time, approximation to the discrete time process (W n), where W n is the congestion window after the n-th pac...
متن کاملSymmetry groups and non-planar collisionless action-minimizing solutions of the three-body problem in three-dimensional space
Periodic and quasi-periodic solutions of the n-body problem can be found as minimizers of the Lagrangian action functional restricted to suitable spaces of symmetric paths. The main purpose of this paper is to develop a systematic approach to the equivariant minimization for the three-body problem in the three-dimensional space. First we give a finite complete list of symmetry groups fit to the...
