Consider a single $M5$ brane on $\mathbb{R}^7\times(\mathbb{R}^4/\mathbb{Z}_N)$, located at the singular point of the $A_N$ singularity and spanning six of the seven directions in…

Consider type IIA string theory on $\mathbb{R}^{10}$ with one $NS5$ brane on $\mathbb{R}^6\subset\mathbb{R}^{10}$, where $x_6,\ldots,x_9=0$, together with $k$ semi-infinite $D6$ br…

Let $Y$ be the complexified target and let $\widetilde Y$ be its mirror. Assume the canonical coisotropic brane on $Y$ has mirror brane $\widetilde{\mathcal B}_{cc}$, obtained as t…
