Description
We argue that an Euclidean supergravity vacuum solution of the form $\mathbb{R}\times S^1\times \mathbb{T}^8$ with imaginary self-dual $F_1$-flux through $\mathbb{R}\times S^1$ is the natural end to the chain of AdS$_d\times S^d\times \mathbb{T}^{10-2d}$-vacua with imaginary self dual $F_d$ flux, where $d\leq 5$. Such vacua come from the near-horizon of D($d-2$)/D($8-d$) branes and are supersymmetric for odd values of $d$. For $d=1$ we suggest that the hallmark of conformal symmetry for the matrix model dual is a vanishing partition function. The matrix dual was recently constructed by [Billo et al., 2021] by adding matrix interactions coming from strings stretching between the D-1 and D7 branes to the IKKT matrix model. We find that the corresponding supergravity solution indeed has vanishing on-shell action. Specific $F_5$ fluxes need to be switched on as a consequence of a T-dual version of the Hanany-Witten effect.
