Cusp region

Fig. 6.8. (a) Schematic three-dimensional representation of the stationary-state surface (1 — ass)-tres- 0 showing the folding at low autocatalyst inflow concentrations which gives rise to ignition, extinction, and multiplicity, (b) The projection onto the P0-t , parameter plane of the two lines of fold points in the stationary-state surface, forming a typical cusp at P0 = gT,e> = 7 inside this cusp region the system has multiple stationary states outside, there is... 

Magnetosphere cusps Regions in the northern and southern polar areas separating the magnetic fields that form the dayside magnetopause from those fields that stretch into the magnetotail. 

X 10l6 ions and (ii) reduction in background pressure, perhaps by the use of preionized plasma in the cusp region for prompt space-charge neutralization. 

At the higher quadruple- and quintuple-zeta levels, the description of the helium ground state appears to be quite accurate everywhere except in the cusp region - for the analytical as well as the...
