Classification of Modular Symmetries in Type IIB Flux Landscape
Keiya Ishiguro, Takafumi Kai, Tatsuo Kobayashi +2
In this work, we study modular symmetries in type IIB flux landscape by investigating symplectic basis transformations of period vectors on toroidal orbifolds. To fix explicit cycl…

More on 8d non-supersymmetric branes and heterotic strings
Yuta Hamada, Arata Ishige, Yuichi Koga
We determine the maximal gauge groups arising in heterotic string theory on . Our analysis proceeds along two approaches. First, we start the moduli space of the supersy…

Classification of Modular Symmetries in Non-Supersymmetric Heterotic String theories
Shuta Funakoshi, Yuichi Koga, Hajime Otsuka
We study modular symmetries in non-supersymmetric heterotic string theories on toroidal backgrounds with Wilson line modulus, constructed by stringy Scherk-Schwartz compactificatio…
