Abstract

We study homological mirror symmetry of the singular hypersurface X0=V(tn+1x0 ⁣xn)Pn+1X_0=V(t^{n+1}-x_0\dotsi x_n)\subseteq\mathbb{P}^{n+1}. Following an SYZ type approach, we produce an LG-model, whose Fukaya-Seidel category recovers line bundles on X0X_0. As a byproduct of our approach, we answer a conjecture of N.Sheridan about generating the small component of the Fukaya category of the smooth index 1 Fano hypersurface in Pn+1\mathbb{P}^{n+1}, without bounding co-chains.
