1. Unsolved Problems
Next: Bibliography Up: R Coronae Borealis Stars Previous: Other Hydrogen-Deficient Stars . ... It remains to be shown that pulsations in all RCB stars provide the necessary conditions for dust nucleation to occur at this distance. ... The strength of a stellar absorption line represents the ratio of line opacity to continuous opacity in the atmosphere; both are related to the number density of the absorbing atoms and so provide the number ratio of line absorbers to continuum absorbers. ...

9. Conditions for Global Synchronization - Bif. and Chaos
... Email: chaos@mail.cplire.ru . ... We investigate phenomena on the edge of spatially homogeneous chaotic mode and spatiotemporal chaos in a lattice of chaotic 1-D maps with local connections. We show that spatially homogeneous chaotic mode cannot exist in a lattice with local connections if the Lyapunov exponent of the isolated chaotic map is greater than some critical positive value. We propose a few schemes that make spatial synchronization possible in large lattices. ...
