Zero set of x^3 - y^5 - z^2, the E8 singularity

Author

Description

Zero set of function f(x,y,z) = x^3 - y^5 - z^2: the E8 singularity for function from R^3 to R.

This model is one of a collection of the zero sets of singularities of functions from R³ to R.

This model shows the zero set f^-1(0) for the E₈ singularity: f(x,y,z) =x³-y⁵-z².

Singularities of functions from Rⁿ to R were clasified by V.I. Arnold [1], an introduction to singularity theory can be found in [2]. The models were calculated using the Liverpool Surface Modelling Package [3,4,5] and JavaView [6].

Model produced with: Liverpool Surface Modeling Package 2.9 and JavaView
