Instability patterns, wakes and topological limnit sets
R. M. Kiehn
Many hydrodynamic instability patterns can be put into correspondence with a subset of characteristic surfaces of tangential discontinuities. These topological limits sets to syste…
Topology and Turbulence
R. M. Kiehn
Over a given regular domain of independent variables {x,y,z,t}, every covariant vector field of flow can be constructed in terms a differential 1-form of Action. The associated Car…
Some closed form solutions to the Navier Stokes equations
R. M. Kiehn
An algorithm for generating a class of closed form solutions to the Navier-Stokes equations is suggested, with examples. Of particular interest are those exact solutions that exhib…
Topological-Torsion and Topological-Spin as coherent structures in plasmas
R. M. Kiehn
The PDE's of classical electromagnetism can be generated from two exterior differential systems that distinguish topologically the field intensities and potentials, F-dA= 0, from t…
Cartan's topological structure
R. M. Kiehn, Phil Baldwin
A system of differential forms will establish a topology and a topological structure on a domain of independent variables such that is possible to determine which maps or processes…
Chirality and helicity in terms of topological spin and topological torsion
R. M. Kiehn
In this article the concept of enantiomorphism is developed in terms of topological, rather than geometrical, concepts. Chirality is to be associated with enantiomorphic pairs whic…
