Tom & Jerry Unprojection triples

Abstract: Unprojection is a theory in Commutative Algebra due to Miles Reid which constructs and analyses more complicated rings from simpler ones.

The talk will be about a new format of unprojection which we call Tom & Jerry triples. The motivation is to construct codimension $6$ Gorenstein rings starting from codimension $3$. As an application we will construct two families of codimension $6$ Fano $3$-folds in weighted projective space.
