Nonlinear Modes Of Liquid Drops As Solitary Waves, Andrei Ludu, J. P. Draayer
Nonlinear Modes Of Liquid Drops As Solitary Waves, Andrei Ludu, J. P. Draayer
Publications
The nonlinear dynamic equations of the surface of a liquid drop are shown to be directly connected to Korteweg–de Vries (KdV) systems, giving traveling solutions that are cnoidal waves. They generate multiscale patterns ranging from small harmonic oscillations (linearized model), to nonlinear oscillations, up through solitary waves. These non-axis-symmetric localized shapes are also described by a KdV Hamiltonian system. Recently such “rotons” were observed experimentally when the shape oscillations of a droplet became nonlinear. The results apply to droplike systems from cluster formation to stellar models, including hyperdeformed nuclei and fission.
Some Root Invariants And Steenrod Operations In Ext_A(F2,F2), Robert R. Bruner
Some Root Invariants And Steenrod Operations In Ext_A(F2,F2), Robert R. Bruner
Mathematics Faculty Research Publications
We give the results of computations of root invariants in Ext over the Steenrod algebra through the 25-stem, with partial information through the 45-stem. This allows the computation of some new Steenrod operations as well.
Some Remarks On The Root Invariant, Robert R. Bruner
Some Remarks On The Root Invariant, Robert R. Bruner
Mathematics Faculty Research Publications
We show how the root invariant of a product depends upon the product of the root invariants, give some examples of the equivariant definition of the root invariant, and verify a weakened form of the algebraic Bredon-Löffler conjecture.
