Abstract

In this paper we study piecewise linear (PWL) vector fields F(x,y) = [ F-+(x,F-y) where x= (x,y) is an element of R-2, F+ (x) = A-Fx b(+) and F- (x) = +, A+ = (at) and A = (a7) are (2 x 2) constant matrices, b+ = (biF,11) E R2 1.1 and b- = (111-, b2-) E IR2 are constant vectors in R2. We suppose that the equilibrium points are saddle or focus in each half-plane. We establish a correspondence between the PWL vector fields and vectors formed by some of the following parameters: sets on E (crossing, sliding or escaping), kind of equilibrium (real or virtual), intersection of manifolds with E, stability and orientation of the focus. Such vectors are called configurations. We reduce the number of configurations by an equivalent relation. Besides, we analyze for which configurations the corresponding PWL vector fields can have or not closed sliding poly-trajectories. (AU)
