nLab Anderson duality

Idea

The stable (infinity,1)-category of spectra has a dualizing object (dualizing module) on a suitable subcategory of finite spectra. It is called the Anderson spectrum $I_{\mathbb{Z}}$ (Lurie, Example 4.3.9). The duality that this induces is called Anderson duality.

Examples

The Anderson dual of the sphere spectrum is discussed in

• (Hopkins-Singer 05, appendix B) in the context of constructing a quadratic refinement of the intersection pairing on ordinary differential cohomology

• in (Freed 14, section 5.1.1) in the context of invertible extended topological field theories.

The Anderson dual of KU is (complex conjugation-equivariantly) the 4-fold suspension spectrum $\Sigma^4 KU$ (Heard-Stojanoska 14, theorem 8.2). This implies that, nonequivariantly $KU$ is Anderson self-dual and the Anderson dual of $KO$ is $\Sigma^4KO$, which were both first proven by Anderson.

Similarly Tmf$[1/2]$ is Anderson dual to its 21-fold suspension (Stojanoska 12).
