On Log Canonical Models of the Moduli Space of Stable Pointed Curves
نویسنده
چکیده
n≥0 Γ(nKMg). Mg has been proven to be of general type for g ≥ 22 [EH,Fa,HaMu]. In particular in this case the finite generation of the canonical ring implies that the canonical model is birational to Mg. Recent progress has been made in this area. For example [BCHM] have proved the existence of canonical models in the case of smooth projective varieties of general type. A somewhat easier problem is to study the log canonical model associated to the graded ring ⊕

MODULI OF WEIGHTED POINTED STABLE CURVES AND LOG CANONICAL MODELS OF Mg,n
We establish nefness of certain tautological divisor classes onM0,n, and more generally on Hassett’s spacesMg,A, and prove thatMg,A is a log canonical model ofMg,n for every genus g and every weight vector A.
متن کاملPROJECTIVITY OF THE MODULI SPACE OF α-STABLE CURVES AND THE LOG MINIMAL PROGRAM FOR Mg,n
For the moduli stacks of α-stable curves defined in [AFSv14], we prove nefness of natural log canonical divisors generalizing a well-known result of Cornalba and Harris for Mg,n. We deduce the projectivity of the good moduli spaces of α-stable curves and identify these moduli spaces with the log canonical models of Mg,n.
متن کاملLog Canonical Singularities and Complete Moduli of Stable Pairs
0.1. This paper consists of two parts. In the first part, assuming the log Minimal Model Program (which is currently only known to be true in dim ≤ 3), we construct the complete moduli of “stable pairs” (X,B) of projective schemes with divisors that generalize the moduli space of n-pointed stable curves Mg,n to arbitrary dimension. The construction itself is a direct generalization of that of [...
متن کاملLog Minimal Model Program for the Moduli Space of Stable Curves of Genus Three
In this paper, we completely work out the log minimal model program for the moduli space of stable curves of genus three. We employ a rational multiple αδ of the divisor δ of singular curves as the boundary divisor, construct the log canonical model for the pair (M3, αδ) using geometric invariant theory as we vary α from one to zero, and give a modular interpretation of each log canonical model...
متن کاملChow Quotients of Grassmannians Ii
1.0 Properties of M0,n ⊂ M0,n. (1) M0,n has a natural moduli interpretation, namely it is the moduli space of stable n-pointed rational curves. (2) Given power series f1(z), . . . , fn(z) which we think of as a one parameter family in M0,n one can ask: What is the limiting stable n-pointed rational curve in M0,n as z → 0 ? There is a beautiful answer, due to Kapranov [Kapranov93a], in terms of ...
