Abstract
The first aim of this thesis is to give a unified and self-contained treatment of a number of known results related to the theory of herds. This gives us the technical tools to deal with the second aim of our work which is to obtain some new results about herds and coherds in the pure categorical setting. A herd at this level is a pretorsor τ : Q → QPQ satisfying associativity and unitality properties with respect to a formal dual structure M = (A, B, P,Q, σᴬ, σᴮ) ....File in questo prodotto:
