This article reveals some features of the “Salam” contract which refers to purchase a commodity for deferred delivery in exchange immediate payment. The structure Salam Contract changes logic ordinary sales contracts, hereby focuses on differentiation between pre-paid one hand and goods (bay’) concept advanced payment other hand. Part 2 highlights as type pre-delivery finance instrument based I...

We explore supersymmetric Type I string-motivated three-family scenarios in which the Standard Model is embedded within two sets of intersecting D branes with U(1)-extended Pati-Salam gauge groups. We study a model inspired by the Shiu-Tye Type IIB orientifold, in which a three-family scenario is obtained by assuming that the gauge symmetry breaking takes place in two stages; the Pati-Salam gro...

The Al-Salam & Carlitz polynomials are q-generalizations of the classical Hermite polynomials. Multivariable generalizations of these polynomials are introduced via a generating function involving a multivariable hypergeometric function which is the q-analogue of the type-A Dunkl integral kernel. An eigenoperator is established for these polynomials and this is used to prove orthogonality with ...

In supersymmetric theories with extra dimensions, the Higgs and matter fields can be part of the gauge multiplet, so that the Yukawa interactions can arise from the gauge interactions. This leads to the possibility of gauge–Yukawa coupling unification, gi = yf , in the effective four dimensional theory after the initial gauge symmetry and the supersymmetry are broken upon orbifold compactificat...
