We consider the Laplacian coflow of a G2-structure on warped products of the form M7=M6×fS1 with M6 a compact 6-manifold endowed with an SU(3)-structure. We give an explicit reinterpretation of this flow as a set of evolution equations of the differential forms defining the SU(3)-structure on M6 and the warping function f. Necessary and sufficient conditions for the existence of solution for this flow are given. Finally we describe new solutions for this flow where the SU(3)-structure on M6 is nearly Kähler, symplectic half-flat or balanced.

G 2-结构翘曲的拉普拉斯同流

我们考虑一个的拉普拉斯协流 G2结构形式的翘曲产品 中号7=中号6×F小号1个中号6 紧凑的6流形,具有 3-结构体。我们对该流进行了明确的重新解释,将其定义为一组定义微分形式的演化方程。3-结构上 中号6和翘曲函数f。给出了用于该流的解的存在的充要条件。最后,我们描述了针对该流程的新解决方案,其中3-结构上 中号6 几乎是Kähler,辛半平坦或平衡的。
