The mechanism of formation of oscillons — localized oscillatory structures

A formal model mechanism of oscillon formation is proposed. These structures were found in avariety of physical systems and a chemical Belousov–Jabotinsky reaction proceeding in an aerosol OT water-in-oil microemulsion. Via the proposed mechanism oscillons occur as a result of interaction of two subsystems. In the first subsystem for a proper set of parameters solitary stationary structures may arise as a result of hard local excitation. These structures influence spatial distribution of the second subsystem parameter that leads to local oscillations in the subsystem.
