3-manifolds Which Admit Finite Group Actions

We prove several results which support the following conjectures: (1) Any smooth action of a finite group on a geometric 3-manifold can be conjugated to preserve the geometric structure. (2) Every irreducible closed 3-manifold M with infinite nx(M) is finitely covered by a Haken 3-manifold.

Complex Projective Structures

In this chapter we discuss the theory of complex projective structures on compact surfaces and its connections with Teichmüller theory, 2-and 3-dimensional hyperbolic geometry, and representations of surface groups into PSL 2 (C). Roughly speaking, a complex projective structure is a type of 2-dimensional geometry in which Möbius transformations play the role of geometric congru-ences (this is ...

Convex Real Projective Structures on Compact Surfaces

The space of inequivalent representations of a compact surface S with χ(S) < 0 as a quotient of a convex domain in RP by a properly discontinuous group of projective transformations is a cell of dimension

Moduli of Reflexive Sheaves on Smooth Projective 3-folds

We compute the expected dimension of the moduli space of torsionfree rank 2 sheaves at a point corresponding to a stable reflexive sheaf on a class of smooth projective threefolds; this class includes Fano and Calabi-Yau threefolds. Further, we show there are only two types of complete intersection Fano threefolds for which this dimension could be zero, and in each case we give an example where...

Projective 3-folds of General Type with Χ = 1

There are many examples of 3-folds of general type with χ(O) = 1 found by Fletcher and Reid about twenty years ago. Fletcher has ever proved P12(X) ≥ 1 and P24(X) ≥ 2 for all minimal 3-folds X of general type with χ(OX) = 1. In this paper, we improve on Fletcher’s method. Our main result is that φm is birational onto its image for allm ≥ 63. To prove this we will show Pm ≥ 1 for all m ≥ 14 and ...
