Webgof a q foliation, you can go backward to obtain a codimension-qfoliation. This de nition breaks down the structure of a foliation into two parts (q structures and sub-mersions), both of which seem more homotopy-theoretic than the original de nition. We have the following homotopy-theoretic notion of equivalence of foliations: De nition 2.3. WebFoliation. Foliation is defined as a pervasive planar structure that results from the nearly parallel alignment of sheet silicate minerals and/or compositional and mineralogical layering in the rock.
