Front propagation and selection in a two-space diblock copolymer melt

The selection problem for propagating fronts is considered for a multiple-mode semilinear parabolic partial differential equation describing front propagation phenomena in a two-space diblock copolymer melt. Several regimes, defined by the value of a reduced temperature appearing in the equation, displaying qualitatively different types of behavior, are identified. It is found that for any value of the reduced temperature in a certain range …
