Intersection of complex sphere and cone

Click For Summary
SUMMARY

The intersection of the complex sphere defined by the equation |z1|^2 + |z2|^2 + |z3|^2 = 1 and the complex cone described by z1^2 + z2^2 + z3^3 = 1 in C^3 forms a smooth submanifold of C^3. The discussion centers on determining the appropriate regular value for the level set, specifically whether to use (1,0) or (1,1,0). The preimage of the point (1,1,0) is identified as the intersection of these two geometric structures.

PREREQUISITES
  • Understanding of complex geometry and submanifolds

Show the intersection of complex sphere (|z1|^2+|z2|^2+|z3|^2=1) in C^3 and the complex cone (z1^2+z2^2+z3^3=1) in C^3 is a smooth submanifold of C^3.

I am trying to do it using regular level set, but I am not sure which one of (1,0) or (1,1,0) should be set to be the regular value?

You have a map from C^3 to R x C. The intersection is the preimage of (1,1,0).
