DESCRIPTION:Sean Tilson\n(University of Osnabrück)\nMultiplicative struct
 ure and power operations have been used to great effect in many familiar s
 pectral sequences. One main application is an easy proof of the collapse o
 f a spectral sequence or a computation of the multiplicative structure or 
 power operations on the target of a spectral sequence. In the case of the 
 Adams spectral sequence one can do more. In his thesis\, Bruner gave defin
 itive formulas for differentials in the Adams spectral sequence of an H_oo
 -ring spectrum. In particular\, this gives a nice intuitive explanation of
  the Hopf invariant one differential d_2(h_{i+1})=h_0h_i^2. In explaining 
 this differential\, we will expose the moving parts of such a result. We w
 ill also present a C_2-equivariant form of some of Bruner's results.
