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).

Fuzzy mathematics. An introduction for engineers and scientists. 2nd ed. (English) Zbl 1009.03002
Studies in Fuzziness and Soft Computing. 20. Heidelberg: Physica-Verlag. xiii, 310 p. DM 138.00; sFr. 119.84; £48.00; $ 84.00 (2001).

This is a slightly expanded version of the first edition (1998; Zbl 0956.03046), and again it is a nice and valuable presentation of seriously “fuzzified” tools of standard applied mathematics.

Chapters 1 to 4 remained unchanged. The other two chapters have been slightly modified and extended. In Chapter 5 on “Fuzzy geometry” the authors now also present results (of A. Rosenfeld and co-workers) from the late 1980s on degrees of adjacency and surroundness, on image enhancement and thresholding via fuzzy compactness, and on Hausdorff distances between fuzzy sets. In Chapter 6 on “Fuzzy abstract algebra” recent results (mainly of the first named author) are added on (local) solutions of nonlinear systems of fuzzy intersection equations of fuzzy singletons.
