WebDec 16, 2008 · Download PDF Abstract: We consider chiral blocks of four Ramond fields of the N=1 super Virasoro algebra where one of the fields is in the (1,2) representation. We show how the null vector in the (1,2) representation determines the chiral blocks as series expansions. We then turn to the Ising model to find an algebraic method to determine … WebChiral Building Blocks Selection - Enamine. Original and unique. 210 Million novel building blocks. Reliable supply.
