%0 Journal Article %T A Recursion Operator for the Universal Hierarchy Equation via Cartan's Method of Equivalence %A Oleg I. Morozov %J Physics %D 2012 %I arXiv %X We apply Cartan's method of equivalence to find a B\"acklund autotransformation for the tangent covering of the universal hierarchy equation. The transformation provides a recursion operator for symmetries of this equation. %U http://arxiv.org/abs/1205.5748v1
