||On Log $\mathbb Q$-Homology Planes and Weighted Projective Planes |
We classify normal affine surfaces with trivial Makar-Limanov
invariant and finite Picard group of the smooth locus, realizing them
as open subsets of weighted projective planes.
We also show that such a surface admits, up to conjugacy,
one or two $G_a$-actions.
