New Exploration of Phase Portrait Classification of Quadratic Polynomial Differential Systems Based on Invariant Theory

After linear differential systems in the plane, the easiest systems are quadratic polynomial differential systems in the plane. Due to their nonlinearity and their many applications, these systems have been studied by many authors. Such quadratic polynomial differential systems have been divided int...
