Algebraic tori in the complement of quartic surfaces

Abstract

Let BP3B\subset \mathbb{P}^3 be an slc quartic surface. The existence of an embedding Gm3P3B\mathbb{G}_m^3\hookrightarrow \mathbb{P}^3\setminus B implies that BB has coregularity zero. In this article, we initiate the classification of coregularity zero slc quartic surfaces BP3B\subset \mathbb{P}^3 for which P3B\mathbb{P}^3\setminus B contains an algebraic torus Gm3\mathbb{G}_m^3. Equivalently, the classification of cluster type pairs (P3,B)(\mathbb{P}^3,B). Along the way, we give criteria for a log Calabi--Yau pair (X,B)(X,B) over a toric variety TT to be of cluster type.
