In complex dynamics
, the bifurcation locus
of a family of holomorphic functions
informally is a locus
of those maps for which the dynamical behavior changes drastically under a small perturbation of the parameter. Thus the bifurcation locus can be thought of as an analog of the Julia set
in parameter space. Without doubt, the most famous example of a bifurcation locus
is the boundary of the Mandelbrot set
Parameters in the complement of the bifurcation locus are called J-stable.
