Compactifications

Some articles on compactifications, compactification:

F-theory - Compactifications
... as the string theory landscape, with elements or so, is dominated by F-theory compactifications on Calabi–Yau four-folds ...
Tychonoff Space - Properties - Compactifications
... those embeddings where the image of X is dense in K these are called Hausdorff compactifications of X ... of a Tychonoff space X in a compact Hausdorff space K the closure of the image of X in K is a compactification of X ... Among those Hausdorff compactifications, there is a unique "most general" one, the Stone–Čech compactification βX ...
Compactifications of Teichmüller Spaces
... There are several inequivalent compactifications of Teichmüller spaces that have been studied ... Several of the earlier compactifications depend on the choice of a point in Teichmüller space so are not invariant under the modular group, which can be inconvenient ... Thurston later found a compactification without this disadvantage, which has become the most widely-used compactification ...
Riemannian Holonomy - Special Holonomy and Spinors - Applications To String Theory
... play an important role in string theory compactifications ... Most important are compactifications on Calabi–Yau manifolds with SU(2) or SU(3) holonomy ... Also important are compactifications on G2 manifolds ...
