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).

Spirals and phase transitions. (English) Zbl 0866.11048
Takahashi, Yoichiro (ed.), Algorithms, fractals, and dynamics. Proceedings of the Hayashibara Forum ’92: International symposium on new bases for engineering science, algorithms, dynamics, and fractals, Okayama, Japan, November 23-28, 1992 and a symposium on algorithms, fractals, and dynamics, November 30--December 2, 1992, Kyoto, Japan. New York, NY: Plenum Press. 59-62 (1995).
The authors restate results of a previous work [Bull. Soc. Math. Fr. 111, 193-201 (1983; Zbl 0529.10049)] by identifying spirals with systems of interacting particles. After this translation of notions they discover a phase transition for spirals at the critical “temperature” that is exactly the inverse of the box dimension of the spiral. For the entire collection see [Zbl 0842.00042].
