To study the topology of a complex algebraic variety, it is natural to try to understand which homology classes are supported on closed algebraic subvarieties of a given dimension. We will describe classical and recent results on this question, and relate these develoments to the rationality problem, which asks for necessary criteria for a variety to be birational to affine space.
