  • Partner Symmetries, Group Foliation and ASD Ricci-Flat Metrics without Killing Vectors 
    Sheftel, M.B.; Malykh, A.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    We demonstrate how a combination of our recently developed methods of partner symmetries, symmetry reduction in group parameters and a new version of the group foliation method can produce noninvariant solutions of complex ...
  • Recursion Operators and Tri-Hamiltonian Structure of the First Heavenly Equation of Plebański 
    Sheftel, M.B.; Yazıcı, D. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    We present first heavenly equation of Plebański in a two-component evolutionary form and obtain Lagrangian and Hamiltonian representations of this system. We study all point symmetries of the two-component system and, using ...
  • Recursions of Symmetry Orbits and Reduction without Reduction 
    Malykh, A.A.; Sheftel, M.B. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    We consider a four-dimensional PDE possessing partner symmetries mainly on the example of complex Monge-Ampère equation (CMA). We use simultaneously two pairs of symmetries related by a recursion relation, which are mutually ...
