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.

Influence of the inhomogeneity of a medium on the directedness of the simplest sources of elastic waves. (Russian. English summary) Zbl 0571.73030

Zap. Nauchn. Semin. Leningr. Otd. Mat. Inst. Steklova 140, 77-87 (1984).

The boundary-layer method is used to find the initial data for the first correction term of the ray expansion for a longitudinal wave generated by a point expansion centre. Similar results are obtained for a transversal wave generated by a rotation centre.
