Center conditions for a cubic system with two homogeneous in variant straight lines and exponential factors
In this paper for a cubic differential system with a singular pointO(0,0) of acenter or a focus type, having two homogeneous invariant straight lines and exponentialfactors, we determine conditions under which the singular point is a center.
