Group Invariant Solutions without Transversality and the Principle of Symmetric Criticality
I. Anderson, M. Fels, C. Torre
We extend Lie's classical method for finding group invariant solutions to the case of non-transverse group actions. For this extension of Lie's method we identify a local obstructi…
Group Invariant Solutions Without Transversality
I. Anderson, M. Fels, C. Torre
We present a generalization of Lie's method for finding the group invariant solutions to a system of partial differential equations. Our generalization relaxes the standard transve…
Gravitational Waves: Just Plane Symmetry
C. G. Torre
We present some remarkable properties of the symmetry group for gravitational plane waves. Our main observation is that metrics with plane wave symmetry satisfy every system of gen…
Multipeakons and the Classical Moment Problem
Richard Beals, D. H. Sattinger, J. Szmigielski
Classical results of Stieltjes are used to obtain explicit formulas for the peakon-antipeakon solutions of the Camassa-Holm equation. The closed form solution is expressed in terms…
