On one hand one must obtain the full low energy Lagrangians resulting from compactifications from ten to four dimensions.
We note that the state space compactifications are abstract constructions so that the only uniqueness that we may expect is up to homeomorphisms; usually there are many possibilities for a concrete description.

Among the topics are elusive worldsheet instantons in heterotic string compactifications, the Witten equation and the geometry of the Landau-Ginzburg model, algebraic topological string theory, the fibrancy of symplectic homology in cotangent bundles, and the theory of higher rank stable pairs and virtual localization.
From subsequent investigations concept of grills has shown to be a powerful supporting and useful tool like nets and filters, further we get a deeper insight into studying some topological notions such as proximity spaces, closure spaces and the theory of compactifications and extension problems of different kinds.

The first seven chapters cover the usual topics of point-set or general topology, including topological spaces, new spaces from old ones, connectedness, the separation and countability axioms, and metrizability and paracompactness, as well as special topics such as contraction mapping in metric spaces, normed linear spaces, the Frechet derivative, manifolds, fractals, compactifications, the Alexander subbase, and the Tychonoff theorems.
Let (Y, f) and (Z, g) be two compactifications of a topological space X.
In order to describe the physics at infinity we will recur to Penrose's ideas [12] of conformal compactifications of Minkowski spacetime by attaching the light-cones at conformal infinity.
Some remarks on the local path-connectedness of infinite point compactifications.
Ultrafilters, extensions of continuous functions, rings of continuous functions, uniformities, compactifications, and measure theoretic techniques have all been profitably employed to provide methods for defining realcompactness.
