Normal type-2 Fuzzy Rational B-Spline Curve

, 2013
In this paper, we proposed a new form of type-2 fuzzy data points(T2FDPs) that is normal type-2 data points(NT2FDPs). These brand-new forms of data were defined by using the definition of normal type-2 triangular fuzzy number(NT2TFN).

Principal Typings in a Restricted Intersection Type System for Beta Normal Forms with De Bruijn Indices [PDF]

, 2010
The lambda-calculus with de Bruijn indices assembles each alpha-class of lambda-terms in a unique term, using indices instead of variable names. Intersection types provide finitary type polymorphism and can characterise normalisable lambda-terms through ...

M-theory on `toric' G_2 cones and its type II reduction

, 2002
We analyze a class of conical G_2 metrics admitting two commuting isometries, together with a certain one-parameter family of G_2 deformations which preserves these symmetries.

Timelike Hopf Duality and Type IIA^* String Solutions [PDF]

, 1999
The usual T-duality that relates the type IIA and IIB theories compactified on circles of inversely-related radii does not operate if the dimensional reduction is performed on the time direction rather than a spatial one.

Supersymmetric warped solutions from Type IIB orientifold reduction

Journal of High Energy Physics
We construct a family of supersymmetric solutions in Type IIB supergravity of the form WAdS3 × WS3 × T 4, where WAdS3 and WS3 denote a warped anti-de Sitter spacetime and a warped 3-sphere, respectively, while T 4 denotes an internal 4-torus.

Structure Constants of Diagonal Reduction Algebras of gl Type

Symmetry, Integrability and Geometry: Methods and Applications, 2011
We describe, in terms of generators and relations, the reduction algebra, related to the diagonal embedding of the Lie algebra gl_n into gl_n⊕gl_n. Its representation theory is related to the theory of decompositions of tensor products of gl_n-modules.

Consistent Group and Coset Reductions of the Bosonic String

, 2003
Dimensional reductions of pure Einstein gravity on cosets other than tori are inconsistent. The inclusion of specific additional scalar and p-form matter can change the situation.

Five-dimensional N=4, SU(2) X U(1) Gauged Supergravity from Type IIB [PDF]

, 1999
We construct the complete and explicit non-linear Kaluza-Klein ansatz for deriving the bosonic sector of N=4 SU(2)\times U(1) gauged five-dimensional supergravity from the reduction of type IIB supergravity on S^5.

Diagrammar and metamorphosis of coset symmetries in dimensionally reduced type IIB supergravity

, 2004
Studying the reduction of type IIB supergravity from ten to three space-time dimensions we describe the metamorphosis of Dynkin diagram for gravity line "caterpillar" into a type IIB supergravity "dragonfly" that is triggered by inclusion of scalars and ...
