By Jiri Rosický

Brown representability approximates the homotopy category of spectra by means of cohomology functors defined on finite spectra. We will show that if a model category *\mathcal K* is suitably determined by *\lambda*-small objects then its homotopy category *Ho(\mathcal K)* is approximated by cohomology functors defined on those *\lambda*-small objects.
