Abstract

We provide a geometric approach to constructing Lefschetz collections and Landau-Ginzburg homological projective duals from a variation of Geometric Invariant Theory quotients. This approach yields homological projective duals for Veronese embeddings in the setting of Landau-Ginzburg models. Our results also extend to a relative homological projective duality framework.
