The critical potential is studied in two models in the large-$N$ expansion, where finite radii of convergence arise from singularities in the complex plane. At finite $N$, the high…

Let $\rho$ be a solution of the saddle equations, let ${\cal B}_\rho$ be the B-model D-brane associated with that saddle, and consider the large-$N$ expansion of correlators around…

A tensor model is built from a tensor with special permutation symmetries, such as complete symmetry with traces removed or antisymmetry, and one studies its perturbative expansion…

Let $R$ be the tensor rank, and consider the $\operatorname{O}(N)^R$ tensor model built around the complete interaction $\mathcal K_{R+1}$ with optimal scaling. An $R$-bubble is me…

Refined OSV conjecture. The refined black-hole partition function of the $N$ D4-branes should equal the square of the refined topological-string partition function on this local cu…
