A tropical facet is a specific type of face of a tropical polytope, which can be thought of as a geometric structure in tropical geometry. In this context, tropical facets correspond to maximal sets of points that satisfy certain linear conditions in the tropical setting. They play an essential role in understanding the structure and properties of tropical polytopes, as they help define the relationships between the vertices and edges within these geometric objects.
