Consider the type-A and type-B Q-system constructions, and let $F$ be the function controlling the central-charge condition. The zero-central-charge specialization is characterized…

The background is the integrable string theory on $\operatorname{AdS}_3\times S^3\times T^4$. Let model C denote the corresponding Q-system, with Q-functions subject to the stated…

Consider a state in the … -deformed model with given charges can be described in the QSC through the following exponential large-$iu$ asymptotics. These asymptotics are intended to…

Let $E$ be the energy of the spectral problem, let $\hbar$ and $k$ be its parameters, let $E_{\rm eff}$ be the effective energy, and let $d_m(k)$ denote the coefficients determined…

The quantum spectral problem is associated to the local Calabi–Yau geometry ${\mathbb P}^1\times {\mathbb P}^1$, whose non-perturbative effects are described by its quantum periods…
