Titre  Triality in Little String Theories 
Résumé  I discuss a class of little string theories (LSTs) with eight supercharges on the worldvolume of $N$ M5branes probing a transverse $\mathbb{Z}_M$ orbifold. These Mbrane configurations compactified on a circle are dual to $M$ D5branes intersecting $N$ NS5branes on $T^2\times \mathbb{R}^{7,1}$ as well as to Ftheory compactified on a toric CalabiYau threefold $X_{N,M}$. I argue that the K\"ahler cone of $X_{N,M}$ admits three regions associated with weakly coupled quiver gauge theories of gauge groups $[U(N)]^M$, $[U(M)]^N$ and $[U(NM/k)]^k$ where $k=\text{gcd}(N,M)$. These provide lowenergy descriptions of different LSTs. The duality between the first two gauge theories is well known and is a consequence of the Sduality between D5 and NS5branes or the Tduality of the LSTs. The triality involving the third gauge theory is new and I demonstrate it using several examples.
