Singularities of the maximum function over a preimage
Singularities of the maximum function over a preimage
1. Introduction.In this paper generic singularities of maximum (minimum) functions over a preimage are classified in the case of one-dimensional or twodimensional image-space, and preimage-space of dimension not smaller than that of the image-space.It turns out that in the case of general position there are four and thirteen singularities of …
