This talk is the first in a series of three talks about Gamma-spaces, partial abelian monoids and Segal-spaces. 

The topic of this talk is the category of partial abelian monoids: based topological spaces with a partially defined addition.

The main goal of the talk is to see how partial abelian monoids give
rise to spectra and homology theories. The classical approach uses
Γ-spaces, so we will discuss the connection between them and PAMs. It
turns out that there is also a strong relation to the tensor product of
PAMs from the first talk. Moreover, we have already seen that the little
n-cubes give rise to a PAM-ring. This idea will be generalised for an
arbitrary operad, using the language of Γ-spaces.
