In this paper, the reduced dierential transform method is investigated fora nonlinear partial dierential equation modeling nematic liquid crystals, itis called the Hunter-Saxton equation. The main advantage of this methodis that it can be applied directly to nonlinear dierential equations withoutrequiring linearization, discretization, or perturbation. It is a semi analytical-numerical method t...

The Hunter–Saxton equation and the Gurevich–Zybin system are considered as two mutually non-equivalent representations of one and the same Whitham-type equation, and all their common solutions are obtained exactly.

In this paper we develop an existence theory for the Cauchy problem to stochastic Hunter-Saxton equatio, and prove several properties of blow-up its solutions. An important part is continuation solutions equations beyond (wave-breaking). linear noise case, using method (stochastic) characteristics, also study random wave-breaking effects unobserved in deterministic problem. Notably, derive expl...

The Hunter–Saxton equation is the Euler equation for the geodesic flow on the quotient space of the infinite-dimensional group of orientation preserving diffeomorphisms of the unit circle modulo the subgroup of rigid rotations equipped with a right-invariant metric. We establish several properties of this quotient space: it has constant sectional curvature equal to 1, the Riemannian exponential...

We study the Lipschitz stability in time for $\alpha$-dissipative solutions to Hunter-Saxton equation, where $\alpha \in [0,1]$ is a constant. define metrics both Lagrangian and Eulerian coordinates, establish those metrics.
