ON THE UNIQUENESS OF LIMIT CYCLES FOR LIÉNARDLI´LIÉNARD EQUATION: THE LEGACY OF G. SANSONE
2010
unpublished
We give an account of the results about limit cycle's uniqueness for Liénard equations, starting from Levinson-Smith's one to the most recent ones. We present a new uniqueness theorem in the line of Sansone-Massera's geometrical approach.
