Jacobi fields in singular metric on quotient space

I don't think your analyses are correct. Consider the following toy problem which has the same boundary behavior as yours: let domain be $(r,\theta)\in \mathbb{R}\times (0,\infty)$ and set the metric ...

Why is the set of singular points of starlike boundary $\Gamma$ closed?

I agree with you, the sentence looks a bit strange. In fact, the conclusion that $E_1$ is closed is true without the assumption of transversality. Here is how I would prove it. Let $(x_j \mid j \geq ...
