Abstract
We consider a Lienard cubic system with quadratic friction function and suggest a method for constructing such systems with the following distributions of limit cycles around the singular points: ((2, 0), 0), ((0, 2), 0), ((1, 1), 1), ((1, 1), 0), ((1, 0), 1), ((0, 1), 1), ((0, 0), 2), ((0, 1), 2), and ((1, 0), 2).
