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.For the entire collection see [Zbl 0849.00033].
