Pinch point (mathematics)
text:
In geometry, a pinch point or cuspidal point is a type of singular point on an algebraic surface. The equation for the surface near a pinch point may be put in the form where [4] denotes terms of degree 4 or more and v is not a square in the ring of functions. For example the surface 1 − 2 x + x 2 − y z 2 = 0 near the point , meaning in coordinates vanishing at that point, has the form above. In fact, if u = 1 − x , v = y and w = z then { u , v , w } is a system of coordinates vanishing at then
