A new ordered compactification

The Nachbin Compactification via Convergence Ordered Spaces

New Manifolds for Superstring Compactification

We construct new manifolds with SU(3) holonomy that are candidate vacua for superstring theory and give a detailed explanation of the techniques involved. Some of these manifolds have a non-abelian fundamental group and thus can lead to a rank five low energy gauge group. Models with an odd number of generations are obtained. ^Θ* violation is discussed in this context and shown to occur generic...

A study on the catalytic activity of a new acidic ordered mesoporous silica (SBA-15)

SBA-15 is an interesting mesoporous silica material having highly ordered nanopores and a large surface area, which is widely employed as a catalyst. This mesoporous silica due to silanol groups is easily functionalized by various organic materials. A new acidic ordered functionalized mesoporous silica (SBA-15-Aminopropyl-Benzyl-SO3H) has been introduced as an efficient catalyst for ...

A New Massive Type IIA Supergravity from Compactification

We consider the most general form for eleven dimensional supersymmetry compatible with on-shell superfields. This allows for the introduction of a conformal Spin(1, 10) connection. In eleven dimensional Minkowski space this modification is trivial and can be removed by a field redefinition, however, upon compactifica-tion on S 1 it is possible to introduce a non-trivial 'Wilson line'. The resul...
