چکیده
Correlation functions of the global E 8 symmetry currents in the Heterotic 5-brane theory. We consider the 5-brane placed at one end of the world in the Heterotic E 8 × E 8 theory. The low energy theory is a 6 dimensional (1, 0) superconformal theory with E 8 as a global symmetry. We calculate the two-point correlator of the E 8 current in 6 dimensions and in 4 dimensions after compactification on T 2. This correlator is derived in 3 different ways: From field theory, from 11 dimensional supergravity and from F-theory. This paper is a written version of the talk given at the 1998 Trieste Conference on Superfivebranes and Physics in 5+1 Dimensions. The talk presented the work of 1 , where a more elaborate discussion can be found.

Correlators of the Global Symmetry Currents of 4D and 6D Superconformal Theories
We study the two-point correlators of the currents of the E8 global symmetry in the N = (1, 0) superconformal six-dimensional theory as well as in the 4D superconformal theories upon toroidal compactification. From the high-energy behavior of the correlator we deduce that in 4D 10 copies of the superconformal theory with E8 global symmetry can be coupled to an N = 2 E8 gauge theory. We present ...

The Makran Coast (Iranian Coastline of the Oman Sea on the Northern Indian Ocean) plays an important role in country’s future navigation and trade due to its accessibility. In 2014, the Iranian Makran coastline was selected by the PMO to be studied as the Phase 6 in the series of Monitoring and Modelling Studies of Iranian Coasts with all disciplines being in investigated including currents. Al...
متن کاملCalculations of Dihedral Groups Using Circular Indexation
In this work, a regular polygon with $n$ sides is described by a periodic (circular) sequence with period $n$. Each element of the sequence represents a vertex of the polygon. Each symmetry of the polygon is the rotation of the polygon around the center-point and/or flipping around a symmetry axis. Here each symmetry is considered as a system that takes an input circular sequence and g...
متن کاملGeneralized String Functions Of N=1 Space-Time Supersymmetric String Vacua
We present a dual formulation of the construction of N = 2 nonlinear σ-model type conformal field theories with c = 9 which are mainly used as internal sectors of Calabi-Yau heterotic string compactifications. The supercurrents G±(z) and the higher components of the spectral flow superfields X±(z)+ θ±Y ±(z) turn out in each case to be tensor products of two simple currents of a c = 1 and a non-...
متن کاملInvestigation of Geostrophic and Ekman Surface Current Using Satellite Altimetry Observations and Surface Wind in Persian Gulf and Oman Sea
The rise of satellite altimetry is a revolution in the ocean sciences. Due to its global coverage and its high resolution, altimetry classically outperforms in situ water level measurement. Ekman and geostrophic currents are large parts of the ocean’s current, playing a vital role in global climate variations. According to the classic oceanography, Ekman and geostrophic currents can be calculat...
