چکیده
We consider geometric decompositions of aspherical 4-manifolds which fibre over 2-orbifolds. We show that no such manifold admits infinitely many fibrations over hyperbolic base orbifolds and that “most” Seifert fibred 4-manifolds over hyperbolic bases have a decomposition induced from a decomposition of

Geometric Decompositions of 4-dimensional Bundle Spaces
We consider geometric decompositions of aspherical 4manifolds which fibre over 2-orbifolds. We show first that no such manifold admits infinitely many fibrations over hyperbolic base orbifolds. If E is Seifert fibred over a hyperbolic surface B and either B has at most one cone point of order 2 or the monodromy has image in SL(2,Z) then E it has a decomposition induced from a decomposition of B...
متن کاملS2-bundles over 2-orbifolds
Let M be a closed 4-manifold with π = π1(M) 6= 1 and π2(M) ∼= Z, and let u : π → Aut(π2(M)) be the natural action. If π ∼= Ker(u) × Z/2Z then M is homotopy equivalent to the total space of an RP -bundle over an aspherical surface. We show here that if π is not such a product then M is homotopy equivalent to the total space of an S-orbifold bundle over a 2orbifold B. There are at most two such o...
متن کامل$PI$-extending modules via nontrivial complex bundles and Abelian endomorphism rings
A module is said to be $PI$-extending provided that every projection invariant submodule is essential in a direct summand of the module. In this paper, we focus on direct summands and indecomposable decompositions of $PI$-extending modules. To this end, we provide several counter examples including the tangent bundles of complex spheres of dimensions bigger than or equal to 5 and certain hyper ...
متن کاملHeterotic M – Theory Vacua with Five – Branes ∗
We construct vacua of heterotic M–theory with general gauge bundles and five–branes. Some aspects of the resulting low–energy effective theories are discussed. M–theory on the orbifold S/Z2 is believed to describe the strong coupling limit of the E8 × E8 heterotic string [1] and, therefore, constitutes a particularly interesting starting point for M–theory particle phenomenology. At low energy,...
متن کاملInfinite-dimensional versions of the primary, cyclic and Jordan decompositions
The famous primary and cyclic decomposition theorems along with the tightly related rational and Jordan canonical forms are extended to linear spaces of infinite dimensions with counterexamples showing the scope of extensions.
