A Note on Decoupling Conditions for Generic Level ŝl ( 3 ) k and Fusion Rules
We find the solution of the sl(3) k singular vector decoupling equations on 3–point functions for the particular case when one of the fields is of weight w 0 · kΛ 0. The result is a function with non-trivial singularities in the flag variables, namely a linear combination of 2 F 1 hypergeometric functions. This calculation fills in a gap in [1] and confirms the sl(3) k fusion rules determined t...

متن کاملthe effects of multiple intelligences (focus on musical, visual, and linguistic) and direct instruction on learning grammar: a case on iranian efl students at elementary level
1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
Fusion Rules for ŝl ( 2 | 1 ; C ) at Fractional Level
We calculate fusion rules for the admissible representations of the superalgebra ŝl(2|1;C)k at fractional level k = −1/2 in the Ramond sector. By representing 3point correlation functions involving a singular vector as the action of differential operators on the sl(2|1;C) invariant 3-point function, we obtain conditions on permitted quantum numbers involved. We find that in this case the primar...
متن کاملA Note on Rational Succession Rules
Succession rules having a rational generating function are usually called rational succession rules. In this note we discuss some problems concerning rational succession rules, and determine a simple method to pass from a rational generating function to a rational succession rule, both defining the same number sequence. 2
