Classical Formulation
For X and Y spaces of finite type, with Y a finite dimensional CW-complex, there is a spectral sequence, called the classical Adams spectral sequence, converging to the p-torsion in, with E2-term given by
- E2t,s = ExtAt,s(H*(Y), H*(X)),
and differentials of bidegree (r, r − 1).
