The sequence of polynomial $(K_r)_r$ is called the \Index{multiplicative sequence} associated to $Q$.
The sequence of polynomials $(K_r)_r$ is called the \Index{multiplicative sequence} associated to $Q$.
This can be used to define a genus:
The genus $\varphi_Q$ is defined for every compact, oriented, smooth manifold $M$ of dimension $4n$ by
\varphi_Q(M) \coloneqq K_n(p_1, \ldots ,p_n)[M] \in \mathbb{R}
\varphi_Q(M) \coloneqq K_n(p_1, \ldots ,p_n)[M] \in R
with $p_i = p_i(M) \in H^{4i}(M;\mathbb{Z})$.
We put $\varphi_Q(M) \coloneqq 0$ if $4 \nmid n$.
