Compactification of configuration spaces via Hilbert schemes
Laurent Evain
Let F(X,n):= X^n-Δbe the complementary of the union Δof the diagonals of X^n and let U be a quotient of F(X,n) (possibly trivial) by a subgroup of the symmetric group S_n. We const…

Irreducible components of the equivariant punctual Hilbert schemes
Laurent Evain
Let H_{ab} be the equivariant Hilbert scheme parametrizing the 0-dimensional subschemes of the affine plane invariant under the natural action of the one-dimensional torus T_{ab}:=…
