Topology/Manifolds Question: Find for which \(a\) the subset of \(R^3\) given by the equations: \[x^2+y^2+z^2=1\] \[x^4+y^4+z^4=a\] is a smooth curve (that is, a 1-dimensional manifold) in \(R^3\) (possibly an empty one). For various ranges of \(a\), when the curve is smooth, how many ovals will the curve consist of? You may start with a similar planar problem, in the \((x, y)\) plane: depending on the value of \(a\), how many intersection points does the unit circle \(x^2+y^2=1\) have with the curve \(x^4+y^4=a\)?

What?
that * is used like a bookmark so we can see if anyone answers the question I am posting for the same reason
brilliant question..m thinking on it
Ah ok thanks @TuringTest , I look forward to seeing if anyone can find a solution.
