Recursion operators and bi-Hamiltonian structure of the general heavenly equation

M. B. Sheftel, A. A. Malykh, D. Yazıcı

We discover two additional Lax pairs and three nonlocal recursion operators for symmetries of the general heavenly equation introduced by Doubrov and Ferapontov. Converting the equ…
