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).

Wave operator for the system of the Dirac-Klein-Gordon equations. (English) Zbl 1221.35246
The extremely technical nature of the problem makes it difficult even to formulate the result of the authors in a short review and down-right impossible to do justice to its proof. So it must suffice here to say that the paper improves upon the regularity conditions on the data required in [{\it R. B. E. Wibowo}, Nonlinear Anal., Theory Methods Appl. 71, No. 3--4, A, 881--890 (2009; Zbl 1167.35427)].
