Extreme plurisubharmonic singularities

Alexander Rashkovskii (2012)

Annales Polonici Mathematici

Similarity:

A plurisubharmonic singularity is extreme if it cannot be represented as the sum of non-homothetic singularities. A complete characterization of such singularities is given for the case of homogeneous singularities (in particular, those determined by generic holomorphic mappings) in terms of decomposability of certain convex sets in ℝⁿ. Another class of extreme singularities is presented by means of a notion of relative type.

Singularities and equicontinuity of certain families of set-valued mappings

Tiberiu Trif (1998)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

In the present paper we establish an abstract principle of condensation of singularities for families consisting of set-valued mappings. By using it as a basic tool, the condensation of the singularities and the equicontinuity of certain families of generalized convex set-valued mappings are studied. In particular, a principle of condensation of the singularities of families of closed convex processes is derived. This principle immediately yields the uniform boundedness theorem stated...
