Abstract:

We study a planar piecewise linear differential system with three zones and asymmetry <(x)over dot> = F(x)-y, <(y)over dot> = g(x), where xg(x) > 0 for x not equal 0 and the graph of F(x) is a U-shaped curve. The system was researched in Llibre et al. (2015) for its limit cycles. However, the number and hyperbolicity of limit cycles were still unclear in some parameter regions. We give the exact number of limit cycles and obtain the hyperbolicity of limit cycles in these parameter regions, where the maximum number is two. (C) 2018 Elsevier B.V. All rights reserved.
