On Structure Constants of sl(2) Theories
Structure constants of minimal conformal theories are reconsidered. It is shown that ratios of structure constants of spin zero fields of a non-diagonal theory over the same evaluated in the diagonal theory are given by a simple expression in terms of the components of the eigenvectors of the adjacency matrix of the corresponding Dynkin diagram. This is proved by inspection, which leads us to c...

15 صفحه اولthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Investigating Islamic Revolution of Iran Based on Agency-Structure in the Theories of International Relations
While communism and capitalism were competing to extend to larger geographical regions, Islamic revolution of Iran founded a political system based on an Islamic ideology and a new player with new standards was introduced as a new agency in the international system. Necessities of an Islamic ideology posed challenges for the interaction of this new agency with established international structur...
متن کاملOn Chevalley’s formula for structure constants
Suppose g = a semi-simple Lie algebra over C G = the corresponding adjoint group B = a Borel subgroup of G T = a Cartan subgroup of B b, t = corresponding Lie algebras Σ = roots corresponding to the choice of t ∆ = simple roots corresponding to the choice of b W = the Weyl groupNG(T )/T . For each α in ∆, let eα 6= 0 be an element of the root space gα. The triple (b, t, {eα}) is called a frame ...
