Query: Geometry and Algebra of the Deltoid Map   The geometry of the deltoid curve gives rise to a self-map of $\mathbb{C}^2$
that is expressed in coordinates by $f(x,y) = (y^2 - 2x, x^2 - 2y)$. This is
one in a family of maps that generalize Chebyshev polynomials to several
variables. We use this example to illustrate two important objects in complex
dynamics: the Julia set and the iterated monodromy group.
