$A_{\infty}$ singularity
For $\mu \ge 0,$ the $A_{\mu}$ series of map germs $f : (\mathbb{R}^n,0) \to (\mathbb{R},0)$ is, for $\varepsilon_i = \pm 1$, given by $f(x) = \varepsilon_1x_1^2 + \cdots + \varepsilon_{n-1}x_{n-1}^2 …

I have two regular surfaces in three space, both of which are given by an equation. I would like to measure the contact between the two surfaces using only their equations. Usually, one would find a l …
