Forgetful linear systems on the projective space and rational normal curves over ℳ0,2nGIT
Let ℳ0,n be the moduli space of n-pointed rational curves. The aim of this note is to give a new geometric construction of ℳ 0 , 2 n GIT , the GIT compactification of ℳ0,2n, in terms of linear systems on ℙ2n−2 that contract all the rational normal curves passing …
