Niemeier格与K3群
Niemeier Lattices and K3 Groups
摘要:
本文考虑K3曲面X在交错群A_5上的作用。我们证明了如果一个循环扩张A_5 . C_n作用于X则n = 1,2或4。我们还确定了K3格的A_5-不变子格及其判别式。
英文摘要:
In this note, we consider K3 surfaces X with an action by the alternating group A_5. We show that if a cyclic extension A_5 . C_n acts on X then n = 1, 2, or 4. We also determine the A_5-invariant sublattice of the K3 lattice and its discriminant form.
