Abstract
We present an Eilenberg-MacLane-type description for the first, second and third spaces of the spectrum defined by a symmetric monoidal category.

When a small category A is equipped with a symmetric monoidal structure, the group completion of its classifying space BA is an infinite loop space
Summary
The homotopy theory of categorical structures is nowadays a relevant part of the machinery in algebraic topology and algebraic K -theory. The set Z1(C, A ) is pointed by the zero 1 -cocycle 0 = (10, 0) , which is defined by 0(c) = 0 , for any object c of C , and 10(σ) = 10 , for any morphism σ of C .
