Twist transition of nematic hyperbolic hedgehogs.
Stability of an idealized hyperbolic hedgehog in a nematic liquid crystal against a twist transition is investigated by extending the methodology of Rüdinger and Stark [Liq. Cryst. 26, 753 (1999)], where the hedgehog is confined between two concentric spheres. In the ideal hyperbolic-hedgehog the molecular orientation is assumed to rotate proportionally with respect to the inclination angle, θ ...
متن کاملOn the Elliptic-hyperbolic Transition in Whitham
The dispersionless Whitham modulation equations in one space dimension and time 4 are generically hyperbolic or elliptic, and breakdown at the transition, which is a curve in the 5 frequency-wavenumber plane. In this paper, the modulation theory is reformulated with a slow 6 phase and different scalings resulting in a phase modulation equation near the singular curves which 7 is a geometric for...
متن کاملA strictly hyperbolic equilibrium phase transition model
This Note is concerned with the strict hyperbolicity of the compressible Euler equations equipped with an equation of state that describes the thermodynamical equilibrium between the liquid phase and the vapor phase of a fluid. The proof is valid for a very wide class of fluids. The argument only relies on smoothness assumptions and on the classical thermodynamical stability assumptions, that r...
متن کاملHyperbolic 3-manifolds and the geometry of the curve complex
We give a brief survey of some recent work on 3-manifolds, notably towards proving Thurston’s ending lamination conjecture. We describe some applications to the theory of surfaces and mapping class groups.
متن کاملThe hyperbolic/elliptic transition in the multi-dimensional Riemann Problem
For a continuous self-similar solution to a system of conservation laws, genuine nonlinearity yields Lipschitz continuity at points where the type of the governing system changes. This is a well-known fact in one space dimension, where a constant state ū bifurcates towards a rarefaction wave at a point x/t that equals an eigenvalue λj(ū). We extend this observation to several space dimensions. ...
