K3曲面、模形式和非几何杂种紧化

K3 surfaces, modular forms, and non-geometric heterotic compactifications

Andreas Malmendier, David R. Morrison

摘要:

我们构造非几何紧化通过使用F-理论对偶的杂种弦紧化的两个环面,连同Siegel模形式之间的密切联系亏格2和某些K3曲面的方程。模群将环面的凯勒模、复结构模和威尔逊线模混合在一起,产生弱耦合杂合弦紧化,但没有大半径解释。

英文摘要:

We construct non-geometric compactifications by using the F-theory dual of the heterotic string compactified on a two-torus, together with a close connection between Siegel modular forms of genus two and the equations of certain K3 surfaces. The modular group mixes together the Kähler, complex structure, and Wilson line moduli of the torus yielding weakly coupled heterotic string compactifications which have no large radius interpretation.
