NettetThis paper studies the number of limit cycles in a cubic system with a cusp. By using new results concerning systems of Liénard type, the question of relative position and the maximum number of limit cycles for this system is solved completely.

Duff, limit cycle and rotated vector fields, Ann. Math, 57(1953), 15- 31. NettetWhen δ monotonous changes, more than one neighbouring limit cycles located in the vector fiel of this polynomial system can expand (or reduce) together with the δ. But the expansion (or reduction) of these limit cycles is not surely monotonous. This vector field is like the rotated vector field. top heating and cooling minneapolis
