Sarkisov links for index 1 Fano 3-folds in codimension 4
Published 24 Nov 2020 in math.AG | (2011.12209v3)
Abstract: We classify Sarkisov links from index 1 Fano 3-folds anticanonically embedded in codimension 4 that start from so-called Type I Tom centres. We apply this to compute the Picard rank of many such Fano 3-folds.
