We classify complex surfaces \((M,\,J)\) admitting Engel structures \({\mathcal {D}}\) which are complex line bundles. Namely, we prove that this happens if and only if \((M,\,J)\) has trivial Chern classes. We construct examples of such Engel structures by adapting a construction due to Geiges [7]. We also study associated Engel defining forms and define a unique splitting of TM associated with \({\mathcal {D}}\) J-Engel.

复杂表面上的恩格尔结构

我们对复杂曲面\(((M,\,J)\)进行分类,以允许使用Engel结构\ {{\ mathcal {D}} \},它们是复杂线束。即,我们证明只有当\((M,\,J)\)具有平凡的Chern类时,才会发生这种情况。我们通过改编归因于Geiges的构造来构造此类Engel结构的示例[7]。我们还研究了相关的恩格尔定义形式,并定义了与\({\ mathcal {D}} \)J -Engel相关的TM的唯一拆分。
