Global asymptotic stability for a stationary solution of a system of integro-differential equations describing the formation of liver zones. (English) Zbl 0767.45005
The formation of liver zones is modeled by a system of integro- differential equations. It has previously been proved that one particular stationary solution, characterized by a jump discontinuity at the zone boundary, is asymptotically stable with respect to sufficiently small perturbations of a certain type.
In this paper the author proves that this stationary solution is in fact globally asymptotically stable.
