Spanier-Whitehead duality



Stable Homotopy theory

Monoidal categories




The stable homotopy category Ho(Spec)Ho(Spec) is a symmetric monoidal category via the symmetric smash product of spectra. Monoidal duality in Ho(Spec)Ho(Spec) is called Spanier-Whitehead duality or S-duality .


The explicit interpretation in terms of monoidal duality is (DoldPuppe, theorem 3.1).

Using this one shows that the trace on the identity on Σ + X\Sigma^\infty_+ X – its categorical dimension – is the Euler characteristic of XX.
