Examples

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).

la: chinese Find documents in a given language. ISO 639-1 language codes can also be used.

Un théorème sur les systèmes linéaires de quadriques à Jacobienne indéterminée. (French) Zbl 0555.51012

Stud. Sci. Math. Hung. 17, 325-330 (1982).

L’A. démontre une condition nécessaire et suffisante pour qu’un système linéaire de quadriques d’un espace complexe linéaire \(S_ r\) soit à matrice Jacobienne identiquement nulle en supposant d’abord que la caractéristique de la Jacobienne soit r et après qu’elle soit r-k (k\(\geq 0)\).
