comment Is it possible to classify the indecomposable representations of the wild quiver with one vertex and two arrows using infinite sets of parameters?
Hell Ying Zhou, welcome to MO. I wanted you to know that I flagged this question as being too broad, which means it could be closed. I would encourage you to narrow your question considerably (e.g. to the aspect of wild-representation-type you are most interested in) and post a new version of it.

comment SO$(4)$ (& SO$(n)$) characterization?
@TobiasFritz While I agree that this question is similar to the one in your link. This question seems to focus on $SO(4)$ while the other question focuses on $SO(n)$, $n>4$.

This link appears to be broken. After doing some digging on David Rusin's NIU page, it appears like this is the current version of the link: math.niu.edu/Papers/Rusin/known-math/98/2generators

comment Automorphism of genus 2 surface with 5 fixed points
@WillSawin Thanks! Although if $S^2(2,2,2,2,2)$ exists as a cyclic quotient, the self-homeomorphism on the genus two surface wouldn't correspond to an involution, but rather a symmetry of order 4. Can that be ruled out as well?
