Stable homotopy theory
Stable Homotopy theory
A function spectrum or mapping spectrum is the analog of a mapping space in the context of stable homotopy theory. It makes the stable homotopy category into a closed category, and together with the smash product of spectra into a smmyetric closed monoidal category
Given two spectra and , their function spectrum is the internal hom in a suitable category of spectra.
In the context of generalized (Eilenberg-Steenrod) cohomology the generalized -cohomology of a topological space is given by the homotopy groups of the mapping spectrum .
