Abstract
We will describe more or less combinatorial results on modules, bimodules, complexes and dualities. A commun feature of our constructions of tilting and cotilting-type objects is the big role played by a "cancellation strategy". A possible reason why sometimes also the simplest structures may provide useful information could be the fact that some mathematical objects have more than one aspect (discrete and continuous, combinatorial and topological and so on).
