 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.

The eigenvalue problem for infinite compact complex symmetric matrices with application to the numerical computation of complex zeros of $J\sb 0(z)- iJ\sb 1(z)$ and of Bessel functions $J\sb m(z)$ of any real order $m$. (English) Zbl 0805.65037
Eigenvalues of an infinite complex symmetric matrix are computed as limits of the eigenvalues of its leading submatrices. Convergence properties of this sequence are investigated, and the computation of the zeros of a combination of Bessel functions is used as a numerical example.
