# Super Virasoro Algerbra in string theory [closed]

I'd like to calculate the algebra $${G_r,G_s}$$ for the Ramond sector, or Neuveu-Schwarz Sector for super Strings. The problem is that I don't know how to evaluate the anti-commutator relation between the mode $$\alpha$$ or the commutation relation for the mode $$b_r$$
