symmetric monoidal (∞,1)-category of spectra
For a commutative ring , a quadratic function is a function with elements , , such that for all ,
where is the canonical square function of the multiplicative monoid.
Given a commutative ring and -modules and , an -quadratic function on with values in is a map such that the following properties hold:
Given abelian groups and , a quadratic function on with values in is a map such that the following properties hold:
