Localized autostructures in homogeneous two-dimensional media
A model describing the creation of spatially localized, stable formations (autostructures) in homogeneous dissipative media is proposed {I. S. Aronson etaL, Zh. Eksp. Teor. Fiz. 89, 92 (1985) [Sov. Phys. JETP 62, 52 (1985)]; О. V. Vashkevich etal., Dokl Akad. Nauk SSSR (in press)}. The formulated equations are a generalization of the Swift-Hohenberg model [H. S. Greenside and W. M. Coughran, Phys. Rev. A 30, 398 (1984) ] to the two-component media. The physical mechanisms which account for the formation in nonequilibrium media of structures in the form of solitary polyhedra are identified.
