Global Stability and Local Bifurcations in a Two-Fluid Model for Tokamak Plasma

We study a two-fluid description for high and low temperature components of the electron velocity distribution in an idealized tokamak plasma evolving on a cylindrical domain, and taking into account nonlinear drift effects only. We refine previous results on the laminar steady state stability and include viscosity. Taking the temperature difference as the primary parameter we show that linear ...

Global stability and bifurcations in a delayed discrete population model

We consider a family of difference equations used in population dynamics. First we recall the most relevant results concerning the global stability of the positive equilibrium. Then, using the survival rate as a parameter, we investigate the changes in the dynamics when it ranges between zero (semelparous populations) and one.

Fluid model equations for the tokamak plasma edge

Increasing evidence that the edge plasma plays a crucial role in global tokamak continement motivates this study of two-dimensional (2-D) (0,~) computational models of fluid transport in the edge plasma region. Fluid plasma equations, boundary conditions, and a coupled neutral-plasma model are developed assuming toroidal symmetry. A plasma potential equation~is presented for consistent drift fl...

passivity in waiting for godot and endgame: a psychoanalytic reading

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...

Global stability, local stability and permanence in model food webs.

The dynamical theory of food webs has been based typically on local stability analysis. The relevance of local stability to food web properties has been questioned because local stability holds only in the immediate vicinity of the equilibrium and provides no information about the size of the basin of attraction. Local stability does not guarantee persistence of food webs in stochastic environm...
