Abstract
We show by an example that the equivalence class of singularity of a plurisubharmonic function cannot be determined by the data of its Lelong numbers in a nontrivial sense Such an example is provided by Siutype singular hermitian metrics associated to a line bundle We also show that a Siutype metric has analytic singularities if and only if the section ring of the line bundle is finitely generatedThe author wishes to thank Sébastien Boucksom for his crucial suggestion of using an argument of 2 toward Theorem 35 and Mihai Păun for showing him the proof of Proposition 23 in 2009 He also thanks Mattias Jonsson for telling him Example 25 Nikolay Shcherbina for raising a question on using multiplier ideal sheaves to distinguish psh functions and the anonymous referee for careful reading and helpful comments
