We study the Postnikov tower of the classifying space of a compact Lie group    P  (  n  ,  m  n  )   , which gives obstructions to lifting a topological Brauer class of period   n   to a    P   U   m  n‐torsor, where the base space is a CW complex of dimension    8   . Combined with the study of a twisted version of Atiyah–Hirzebruch spectral sequence, this solves the topological period–index problem for CW complexes of dimension 8.

The topological period–index problem over 8‐complexes, I
