zbMATH — the first resource for mathematics

Geometry Search for the term Geometry in any field. Queries are case-independent.
Funct* Wildcard queries are specified by * (e.g. functions, functorial, etc.). Otherwise the search is exact.
"Topological group" Phrases (multi-words) should be set in "straight quotation marks".
au: Bourbaki & ti: Algebra Search for author and title. The and-operator & is default and can be omitted.
Chebyshev | Tschebyscheff The or-operator | allows to search for Chebyshev or Tschebyscheff.
"Quasi* map*" py: 1989 The resulting documents have publication year 1989.
so: Eur* J* Mat* Soc* cc: 14 Search for publications in a particular source with a Mathematics Subject Classification code (cc) in 14.
"Partial diff* eq*" ! elliptic The not-operator ! eliminates all results containing the word elliptic.
dt: b & au: Hilbert The document type is set to books; alternatively: j for journal articles, a for book articles.
py: 2000-2015 cc: (94A | 11T) Number ranges are accepted. Terms can be grouped within (parentheses).

Set convergences. An attempt of classification. (English) Zbl 0786.54013

During the last ten years there has been a great interest in hyperspaces – partly due to applications and partly due to interesting new ideas. One of the most prolific researchers in this area is Gerald Beer who has recently written a book on it [Topologies on closed and closed convex sets (Mathematics and its Applications, Vol. 268) Kluwer Acad. Publ. 1993].

The authors of this article have also made valuable contributions to the subject and in this article they explore a new method which allows them not only to derive most of the known hypertopologies but also to define some new ones. In the opinion of the reviewer this article will be of great help not only to the established researchers but also to the newcomers to this field.
