Há 1 dia · We will show the following result in Section 2. Theorem 1.1. A tropical fan Σ is homologically smooth if and only if Σ and all its star fans Σσ, σ ∈ Σ, verify tropical Poincaré duality. In this paper, the star fan Σσ refers to the fan in NR Nσ,R induced by the cones η in Σ which contain σ as a face.
