Beauville曲面与有限群

Beauville surfaces and finite groups

Yolanda Fuertes, Gareth Jones

摘要:

推广了Bauer,Catanese和Grunewald以及Fuertes和González-Diez的结果,证明了当q>5时,由群L_2(q)和SL_2(q)以及当e>1时,由Suzuki群Sz(2 ^e)和Ree群R(3 ^e)可以得到非混合型Beauville曲面.我们还证明了L_2(q)和SL_2(q)具有强实Beauville结构,当且仅当q>5时,得到实Beauville曲面。

英文摘要:

Extending results of Bauer, Catanese and Grunewald, and of Fuertes and González-Diez, we show that Beauville surfaces of unmixed type can be obtained from the groups L_2(q) and SL_2(q) for all prime powers q>5, and the Suzuki groups Sz(2^e) and the Ree groups R(3^e) for all odd e>1. We also show that L_2(q) and SL_2(q) admit strongly real Beauville structures, yielding real Beauville surfaces, if and only if q>5.
