Resumen:	In 1960 Markus and Yamabe made the conjecture that if a C1 differential system x˙=F(x) in Rn has a unique equilibrium point and DF(x) is Hurwitz for all x∈Rn, then the equilibrium point is a global attractor. This conjecture was completely solved in 1997 and it turned out to be true in R2 and false in Rn for all n≥3. In (The Markus-Yamabe conjecture for continuous and discontinuous piecewise linear differential systems, 2020) the authors extended the Markus-Yamabe conjecture to continuous and discontinuous piecewise linear differential systems in Rn separated by a hyperplane, they proved for the continuous systems that the extended conjecture is true in R2 and false in Rn for all n≥3, but for discontinuous systems they proved that the conjecture is false in Rn for all n≥2. In this paper first we show that there are no continuous piecewise linear differential systems separated by a conic×Rn-2 except the linear differential systems in Rn. And after we prove that the extended Markus-Yamabe conjecture to discontinuous piecewise linear differential systems in Rn separated by a conic×Rn-2 is false in Rn for all n≥2.
