Geometry of Satake and Toroidal Compactifications
Geometry of Satake Toroidal Compactifications
2014/12/8
In [JM02, section 14], Ji and MacPherson give new constructions of the Borel--Serre and reductive Borel--Serre compactifications [BS73, Zuc82] of a locally symmetric space. They use equivalence classe...
Compactifications of spaces of Landau-Ginzburg models
Compactifications Landau-Ginzburg models Algebraic Geometry
2012/7/9
This paper reviews results and techniques from the authors' previous work "Symplectomorphism group relations and degenerations of Landau-Ginzburg models" and applies them in basic examples. The main e...
On the boundedness of effective potentials arising from string compactifications
the boundedness of effective potentials string compactifications Mathematical Physics
2012/6/30
We study effective potentials coming from compactifications of string theory. We show that, under mild assumptions, such potentials are bounded from below in four dimensions, giving an affirmative ans...
Banach representations and affine compactifications of dynamical systems
affine compactification affine flow Asplund space enveloping semigroup non-sensitivity right topological semigroup
2012/4/18
To every Banach space V we associate a compact right topological affine semigroup E(V). We show that a separable Banach space V is Asplund if and only if E(V) is metrizable, and it is Rosenthal (i.e. ...
Compactifications of Complete Riemannian manifolds and Their Applications
Compactifications Complete Riemannian manifolds Applications
2011/1/21
To study a noncompact Riemannian manifold, it is often useful to find a compactification
or attach a boundary. For example, in hyperbolic geometry a lot of investigation is carried out on the sphere ...
Uniform Eberlein compactifications of metrizable spaces
scattered space metrizable space scattered compactification
2011/1/18
We prove that each metrizable space X (of size |X| c) has a (first countable) uniform Eberlein compactification and each scattered metriz-able space has a scattered hereditarily paracompact compacti...
We give an informal survey, emphasizing examples and open problems, of two interconnected research programs in moduli of curves: the systematic classi cation of modular compacti cations of Mg;n, and t...
Double quiver gauge theory and nearly Kahler flux compactifications
Double quiver gauge theory nearly Kahler flux compactifications
2010/12/15
We consider G-equivariant dimensional reduction of Yang-Mills theory with torsion on manifolds
of the form M × G/H where M is a smooth manifold, and G/H is a compact six-dimensional
homogeneous spac...
Large scale geometry, compactifications and the integral Novikov conjectures for arithmetic groups
Large scale geometry compactifications integral Novikov conjectures arithmetic groups
2018/4/20
The original Novikov conjecture concerns the (oriented) homotopy invariance of higher signatures of manifolds and is equivalent to the rational injectivity of the assembly map in surgery theory. The i...
Successive Toroidal Compactifications of a Closed Bosonic Strings
Closed Bosonic Strings Toroidal Compactifications
2010/4/15
Successive toroidal compactifications of a closed bosonic string are studied and some Lie groups solutions are derived.
