In this paper, we study affine manifolds endowed with linear foliations. These are foliations defined by vector subspaces invariant by the linear holonomy. We show that an n-dimensional compact, complete, and oriented affine manifold endowed with a codimension 1 linear foliation is homeomorphic to the n-dimensional torus if the leaves of are simply connected. Let be a 3-dimensional compact affine manifold endowed with a codimension 1 linear foliation. We prove that has a finite cover which is homeomorphic to the total space of a bundle over the circle if its developing map is injective, and has a convex image.

仿射流形上的线性叶理
在本文中,我们研究了具有线性叶理的仿射流形。这些是由线性完整法不变的向量子空间定义的叶面。我们展示了一个n维紧凑、完整和定向的仿射流形,其具有辅维 1 线性叶理同胚于n维环面,如果只是连接。让是一个 3 维紧凑仿射流形,赋予了一个 codimension 1 线性叶理。我们证明 有一个有限覆盖,如果它的展开图是单射的,它同胚于圆上的丛的总空间,并且有一个凸像。
