Abstract
A restricted curvature model with conservation of total number of particles is introduced. The surface width W of the model grows as t β at the beginning with β≈0.25 and becomes saturated at L α for t≫L z with α≈1.5, where L is the system size. The conservation law leads to a new universality class following sixth-order linear equation with conservative noise. The relation between our model and the equation is discussed.
