## The Steenrod Problem of Realizing Polynomial Cohomology Rings

##### Abstract:

In 1960 Norman Steenrod asked which graded polynomial rings occur as the cohomology ring of a space. Progress on this question has been made throughout the last fifty years, and the final step in its solution was recently given by K. Andersen and myself. My talk will be a survey of this problem and its solution.
