Dual Little Strings from F-Theory and Flop Transitions

Understand

A particular two-parameter class of little string theories can be described by $M$ parallel M5-branes probing a transverse affine $A_{N-1}$ singularity.

• We previously discussed the duality between the theories labelled by $(N,M)$ and $(M,N)$.
• In this work, we propose that these two are in fact only part of a larger web of dual theories.
• We provide evidence that the theories labelled by $(N,M)$ and $(\tfrac{NM}{k},k)$ are dual to each other, where $k=\text{gcd}(N,M)$.
