La 4e de couverture indique :"Monoidal Topology describes an active research area that, after various past proposals on how to axiomatize "spaces" in terms of convergence, began to emerge at the beginning of the millennium. It combines Barr's relational presentation of topologic…
In the first paper, the [script capital] H-coextension problem for monoids is studied in full generality. This is done by means of a factor system technique which reduces to classical group extension theory when all monoids under consideration are groups. This technique is made …

If [italic]k is a commutative ring, the isomorphism classes of [italic]k-algebroids (small [italic]k categories) form a commutative monoid under the tensor product. Moreover, Morita equivalence is a congruence relation on this monoid. It is shown that the group of invertible ele…
