Tangents of plurisubharmonic functions. (English) Zbl 0810.31006

Gong, Sheng (ed.) et al., International symposium on number theory and analysis in memory of Hua Loo Keng, held at the Tsing Hua University, Beijing, China, August 1-7, 1988. Volume II: Analysis. Berlin: Springer- Verlag. 157-167 (1991).
Author’s summary: Local properties of plurisubharmonic functions are studied by means of the notion of tangent which describes the behavior of the function near a given point. We show that there are plurisubharmonic functions with several tangents, disproving a conjecture of Reese Harvey.
