ON A STRATIFICATION OF THE MODULI M0,n(G(2,4),d) AND ENUMERATIVE GEOMETRY
نویسندگان
چکیده
We study the geometry of the moduli space M0,n(G(2, 4), d). We consider a particular stratification of this moduli. As a consequence we compute the degree of the variety parametrizing rational ruled surfaces with a minimal directrix of degree [ d 2 ]− 1 by studying divisors in the moduli space of stable maps.

The Quantum Cohomology of Blow-ups of P and Enumerative Geometry
The enumerative geometry of curves in algebraic varieties has taken a new direction with the appearance of Gromov-Witten invariants and quantum cohomology. Gromov-Witten invariants originate in symplectic geometry and were first defined in terms of pseudo-holomorphic curves. In algebraic geometry, these invariants are defined using moduli spaces of stable maps. Let X be a nonsingular projective...
متن کاملOn the Chow Ring of M 0
We describe the Chow ring with rational coefficients of the moduli space of stable maps with marked points M0,m(P , d) as the subring of invariants of a ring B(M0,m(P , d);Q), relative to the action of the group of symmetries Sd. B (M0,m(P , d);Q) is computed by following a sequence of intermediate spaces for M0,m(P , d) and relating them to substrata of M0,1(P , d + m − 1). An additive basis f...
