#### Abstract

Given an algebraic hypersurface $H = f^{-1} (0)$ in $(\mathbb{C}^{\ast})^n$, homological mirror symmetry relates the wrapped Fukaya category of $H$ to the derived category of singularities of the mirror Landau–Ginzburg model. We propose an enriched version of this picture which also features the wrapped Fukaya category of the complement $(\mathbb{C}^{\ast})^n \setminus H$ and the Fukaya–Seidel category of the Landau–Ginzburg model $(\mathbb{C}^{\ast})^n , f)$. We illustrate our speculations on simple examples, and sketch a proof of homological mirror symmetry for higher-dimensional pairs of pants.
