Title: On symmetries and conservation laws of the Gibbons-Tsarev equation (jointly with H. Baran, P. Blaschke, I.S. Krasil'shchik)
Recently, an infinite-dimensional symmetry algebra of the Gibbons-Tsarev equation has been reported without proof, followed by closed-form formula for the mastersymmetry (Odesskij and Sokolov). We present closed-form formulas for all these symmetries.
