Uniqueness and distribution of limit cycles for bounded quadratic systems (English)
0 references
The author considers bounded quadratic systems with three finite critical points and uses the methods and results of Zhang Pingguang to provide some uniqueness theorems on limit cycles for such systems. He also proves that any bounded quadratic system can not have a \((2,2)\)-distribution of limit cycles according to these uniqueness theorems.
