Curvature evolution of plane curves with prescribed opening angle

Abstract: We discuss the evolution of plane curves which are described by entire graphs with prescribed opening angle. We show that a solution converges to the unique self-similar solution with the same asymptotics.

“…At larger times, the solution is close to a single sinusoidal wave. In the regime of the sinusoidal profile, from (20) decay times are shorter, of the order of the standard time (ℓ/nπ) 2 /B that is familiar from exponential decay of Fourier modes in linear diffusion models (e.g. [10]) when the half-wavelength ℓ/n is the typical distance between neighboring regions of high and low mass concentration.…”

“…Two decades ago [5], the exact solution was constructed in parametric integral form for nonlinear surface evolution near a symmetric grain boundary, with constant slope at the grain boundary groove, initial flatness and zero displacement at infinity. A similar procedure produces the more general "open angle" solutions for deposition in a wedge [20]. Subsequently, the fourth-order Mullins equation for curvature-driven surface diffusion on an almost-isotropic material, was solved with boundary conditions representing a symmetric grain boundary [6,28,7].…”
