| Description | We construct a map from the 3-skeleton of the classifying space for Gamma = SL2 (Z[t,1/t]) to a Euclidean building on which Gamma acts. We then find an infinite family of independent cocycles in the building and lift them to the classifying space, thus proving that the cohomology group H2(SL2 (Z[t,1/t]) ;Q) is infinite-dimensional. |
