对于一个Veech曲面(X, !),我们刻画了X n的Aff + (X, !)不变子空间,证明了非算术Veech曲面只有有限多个非常特殊形状的不变子空间(在任何维度上)。在其他结果中,我们发现(X, !)的副本嵌入在平移曲面的模空间中。我们研究(预)点阵表面的光照问题。对于(X, !)预格,我们证明了在任意X∈X上不能照亮的点的最不可数性。应用我们在不变量子空间上的结果,证明了当(X, !)为Veech时这些集合的有限性。
For a Veech surface (X, !), we characterize Aff + (X, !) invariant subspaces of X n and prove that non-arithmetic Veech surfaces have only finitely many invariant subspaces of very par- ticular shape (in any dimension). Among other consequences we find copies of (X, !) embedded in the moduli-space of translation surfaces. We study illumination problems in (pre-)lattice surfaces. For (X, !) prelattice we prove the at most countableness of points non-illuminable from any x ∈ X. Applying our results on invari- ant subspaces we prove the finiteness of these sets when (X, !) is Veech.
