DESCRIPTION:Title: <a href="https://researchseminars.org/talk/notts_ag/80/
 ">CANCELLED - On accumulation points of volumes of stable surfaces with on
 e cyclic quotient singularity</a>\nby Diana Torres Valencia (University of
  Pamplona) as part of Online Nottingham algebraic geometry seminar\n\n\nAb
 stract\nThe set of volumes of stable surfaces does have accumulation point
 s. I will introduce this phenomenon for surfaces with one cyclic quotient 
 singularity towards answering the question under which conditions we can s
 till have boundedness. Effective bounds allow listing singularities that m
 ight appear on a stable surface after fixing its invariants. I will show o
 ptimal inequalities for stable surfaces with one cyclic quotient singulari
 ty\, which can be used to prove boundedness under certain conditions. I al
 so will introduce the notion of generalized T-singularity\, which is a nat
 ural generalization of the well-known T-singularities. I will show how the
  accumulation points of volumes of stable surfaces with one generalized T-
 singularity are formed.\n
