Query: Differential equations from null vectors of the Ramond algebra   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 differential equations for the blocks of four spin fields. Extending
these ideas to the super Virasoro case, we find a first order differential
equation for blocks of four Ramond fields. We are able to find exact solutions
in many cases. We compare our blocks with results known from other methods.
