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.

Symmetry reduction of asymmetric heavenly equation and \(2+1\)-dimensional bi-Hamiltonian system. (English) Zbl 1300.35126

J. Geom. Symmetry Phys. 34, 87-96 (2014).

Summary: Asymmetric heavenly equation, presented in a two-component form, is known to be \(3+1\)-dimensional bi-Hamiltonian system. We show that symmetry reduction of this equation yields a new two component \(2+1\)-dimensional integrable bi-Hamiltonian system. We prove that this new \(2+1\)-dimensional system admits bi-Hamiltonian structure, so that it is integrable according to Magri’s theorem.
