    For problem 2.2 do we just need to algebraically show those lower bounds or do we also need to show that those bounds are tight, i.e. that there exist surfaces attaining those numbers? For instance, in order to do this problem fully rigorously we would need to give a generic construction (for any g >= 2) of a surface with only 1 irregular valence vertex. But I’m not sure if this is what you’re asking for.

    Just algebraically, though it’s fun (and actually not too hard) to come up with an explicit construction – maybe easiest to see by considering the fundamental polygon of the surface.
