New lower bounds for the Hilbert number of polynomial systems of Liénard type
In this paper, we study the maximal number of limit cycles of some kinds of polynomial Liénard systems with arbitrary degree and obtain some new lower bounds for the Hilbert number of the systems, which improve truly the certain existing results.
