Every Orientable Seifert 3-manifold Is a Real Component of a Uniruled Algebraic Variety
We show that any orientable Seifert 3-manifold is diffeomorphic to a connected component of the set of real points of a uniruled real algebraic variety, and prove a conjecture of János Kollár.
متن کاملStructures of small closed non-orientable 3-manifold triangulations
A census is presented of all closed non-orientable 3-manifold triangulations formed from at most seven tetrahedra satisfying the additional constraints of minimality and P-irreducibility. The eight different 3-manifolds represented by these 41 different triangulations are identified and described in detail, with particular attention paid to the recurring combinatorial structures that are shared...
متن کاملLefschetz Fibrations and 3-fold Branched Covering Spaces
Let M be a smooth 4-manifold which admits a genus g C∞-Lefschetz fibration over S, and assume that all of the vanishing cycles of this fibration are nonseparating curves. We show that M can be obtained as an irregular simple 3-fold cover of an S-bundle over S, branched over an embedded surface. Moreover, for g = 2, we show that M is a cyclic 2-fold cover of an S-bundle over S, branched over an ...
متن کاملLefschetz Fibrations and 3-fold Branched Covering Spaces, Ii
Let M be a smooth 4-manifold which admits a relatively minimal genus h Lefschetz fibration over S, and assume that the collection of vanishing cycles for this fibration includes σ separating curves. For h ≥ 3, we show that M is the relative minimalization of a genus h Lefschetz fibration obtained as an irregular simple 3-fold branched cover of the rational surface CP #(2σ + 1)CP , branched over...
متن کاملSimplification paths in the Pachner graphs of closed orientable 3-manifold triangulations
It is important to have effective methods for simplifying 3-manifold triangulations without losing any topological information. In theory this is difficult: we might need to make a triangulation super-exponentially more complex before we can make it smaller than its original size. Here we present experimental work that suggests the reality is far different: for an exhaustive census of 81 800 39...
