A universal étale lift of a proper local embedding
Anca Mustata, Andrei Mustata
To any finite local embedding of Deligne--Mumford stacks we associate an étale, universally closed morphism such that for the complement of the i…
Tautological rings of stable map spaces
Anca M. Mustata, Andrei Mustata
We find a set of generators and relations for the system of extended tautological rings associated to the moduli spaces of stable maps in genus zero, admitting a simple geometrical…
Universal relations on stable map spaces in genus zero
Anca M. Mustata, Andrei Mustata
We introduce a factorization for the map between moduli spaces of stable maps which forgets one marked point. This leads to a study of universal relations in the cohomology of stab…
The Chow ring of Mbar_{0,m}(n, d)
Anca Mustata, Andrei Mustata
We describe the Chow ring with rational coefficients of the moduli space of stable maps with marked points Mbar_{0,m}(n,d) as the subring of invariants of a ring B, relative to the…
Intermediate Moduli Spaces of Stable Maps
Andrei Mustata, Magdalena Anca Mustata
We describe the Chow ring with rational coefficients of Mbar_{0,1}(P^n,d) as the subring of invariants of a ring B(Mbar_{0,1}(P^n,d);Q), relative to the action of the group of symm…
