Separation of variables and contractions on two-dimensional hyperboloid. Symmetry, Integrability and Geometry: Methods and Applications (SIGMA), 8. http://doi.org/10.3842/SIGMA.2012.105https://hdl.handle.net/10289/10143In this paper analytic contractions have been established in the R → ∞ con- traction limit for exactly solvable basis functions of the Helmholtz equation on the two- dimensional two-sheeted hyperboloid. As a consequence we present some new asymptotic formulae.application/pdfenThe authors retain the copyright for their papers published in SIGMA under the terms of the Creative Commons Attribution-ShareAlike LicenseJournal Article10.3842/SIGMA.2012.1051815-0659
