A staggered-mesh finite-difference numerical method for solving the transport equations in low pressure rf glow discharges
(Elsevier, 1988-07)
A numerical model of a low pressure parallel plate rf glow discharge is presented based on a self-consistent formulation of the energy-momentum conservation equations for electrons, the continuity equations for both electrons ...
Differential operators commuting with invariant functions
(Birkhäuser Verlag; Birkhäuser Verlag, Basel, ; Springer Science+Business Media, 1997-10)
Let be a reductive, complex Lie algebra, with adjoint group G , let G act on the ring of differential operators via the adjoint action and write for the differential of this action. We prove that the commutant, in , of is ...
Immanants of Totally Positive Matrices are Nonnegative

Ultraviolet stability of three-dimensional lattice pure gauge field theories
(Springer-Verlag, 1985-06)
We prove the ultraviolet stability for three-dimensional lattice gauge field theories. We consider only the Wilson lattice approximation for pure Yang-Mills field theories. The proof is based on results of the previous ...
Ion acoustic parametric decay instability in a plasma with [beta] > 1
(Elsevier, 1976-10-04)
It is found that in a plasma with [beta] > 1 a finite amplitude ion acoustic wave is unstable and decays into two shear Alfven waves propagating in opposite directions. The threshold and growth rate of the instability ...
Solutions of the Oppenheimer--Volkoff Equations Inside 9/8$^{ths}$ of the Schwarzschild Radius
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-03)
We refine the Buchdahl 9/8 ths stability theorem for stars by describing quantitatively the behavior of solutions to the Oppenheimer–Volkoff equations when the star surface lies inside 9/8 ths of the Schwarzschild radius. ...
Digraphs with real and gaussian spectra
(Elsevier, 1980-07)
The conventional binary operations of cartesian product, conjunction, and composition of two digraphs D1 and D2 are observed to give the sum, the product, and a more complicated combination of the spectra of D1 and D2 as ...
The exterior Neumann problem for the three-dimensional Helmholtz equation
(Springer-Verlag, 1966-10)
The Stokes Stream Function in Axially Symmetric Potential Theory
