An effective upper bound for Fano indices of canonical Fano threefolds, I
Published 26 May 2025 in math.AG | (2505.19541v1)
Abstract: Let $X$ be a $\mathbb Q$-factorial weak Fano $3$-fold with at worst isolated canonical singularities. We show that the $\mathbb Q$-Fano index of $X$ is at most $61$.
