Saddle-Source (Sink) with Hyperbolic Flow Singularity

In this chapter, saddle source (sink) flows and hyperbolic flow singularity with hyperbolic flows, positive or negative saddles, and center are discussed, and the corresponding networks are presented for saddle source (sink) and hyperbolic flow singularity with simple flow and equilibriums. The corresponding switching bifurcations are discussed through the infinite equilibrium, which includes up-down and down-up infinite equilibriums, inflection source (sink) infinite equilibriums, and two infinite equilibriums of inflection source (sink) and up-down (down-up) saddles.
