Query: Global Behavior of Solutions to Chevron Pattern Equations   Considering a system of equations modeling the chevron pattern dynamics, we
show that the corresponding initial boundary value problem has a unique weak
solution that continuously depends on initial data, and the semigroup generated
by this problem in the phase space $X^0:= L^2(\Omega)\times L^2(\Omega)$ has a
global attractor. We also provide some insight to the behavior of the system,
by reducing it under special assumptions to systems of ODEs, that can in turn
be studied as dynamical systems.
