Bendixson’s negative criterion



be a planar system where 𝐟=(𝐗,𝐘)t and 𝐱=(x,y)t. Furthermore 𝐟∈C1⁒(E) where E is a simply connected region of the plane. If βˆ‚β‘π—βˆ‚β‘x+βˆ‚β‘π˜βˆ‚β‘y (the divergence of the vector field f, βˆ‡β‹…πŸ) is always of the same sign but not identically zero then there are no periodic solution in the region E of the planar system.
