## Julia set

[′jül·yə ‚set]
(mathematics)
For a polynomial, p, with degree greater than 1, the Julia set of p is the boundary of the set of complex numbers, z, such that the sequence p (z), p 2(z), …, pn (z), … is bounded, where p 2(z) = p [p (z)], and so forth.

A point [z.sub.0] is in the Julia set if and only if dynamics in a neighborhood of [z.sub.0] shows strong dependence on the starting conditions, so that nearby initial conditions yield to wildly different behavior after a number of full iterations.
A complex number z (or a + ib) is a member of a Julia set, for a given real number c, if z is the first member of a sequence, defined by an iterative function, which remains bounded.
