Classification of Linear Weighted Graphs Up to Blowing-Up and Blowing-Down We classify linear weighted graphs up to the
blowing-up and blowing-down operations which are relevant for the
study of algebraic surfaces.

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.
