Ansatze are constructed under which the solutions of 11-dimensional supergravity must be stationary points of a parabolic flow on a Riemannian manifold . This parabolic flow turns out to be the Ricci flow coupled to a scalar field, a -form, and a -form. This allows the introduction of techniques from parabolic partial differential equations to the search of solutions to 11-dimensional supergravity. As a first step, Shi-type estimates and criteria for the long-time existence of the flow are established.

11维超重力的抛物线降维
Ansatze 被构建,在该条件下,11 维超重力的解必须是黎曼流形上抛物线流的驻点 . 这个抛物线流被证明是耦合到一个标量场的 Ricci 流,一个- 形式,和 -形式。这允许引入从抛物线偏微分方程到 11 维超引力解的搜索技术。作为第一步,建立流动长期存在的 Shi 型估计和标准。
