Multiplicative generalized cohomology theory
= Multiplicative generalized cohomology theory
{title2=$h^p(X)\otimes h^q(X)\longrightarrow h^{p+q}(X)$}
A <generalized cohomology theory> with natural unital cup products compatible with relative groups, suspension, and the cohomology axioms. Its coefficient groups form a graded ring. Thom orientations make the cohomology of a bundle's <Thom space> a shifted module over the cohomology of the base.
