Fixed Points Features in N-Point Gravitational Lenses

A set of fixed points in N-point gravitational here lenses is studied in the paper.We use complex form of lens mapping to study fixed points.There are some merits of using a complex form over coordinate.In coordinate form gravitational lens is described by a system of two equations and in complex form is described by one equation.We transform compl
