This paper deals with the problem of entry deterrence in two different ways. First, we analyze conditions under which entry prevention is the best strategy for an incumbent firm, and second, we link entry prevention with another important field of industrial organization, the analysis of reasonable conjectures. That entry prevention may be of interest for incumbent firms has been studied by Osb...

More precisely we are concerned with the definition of quotients of this set by coarser and coarser congruences which lead to an extension – in the case of multiplicities – of some classical results stated in the Boolean case. In particular, multiplicity analogues of the well known theorems of Brzozowski and Antim...

While there is consensus that sequential consistency [Lamport 1979] is the strongest memory model, nobody seems to have tried to identify the weakest memory model. This thesis concerns itself with precisely this problem. We cannot hope to identify the weakest memory model unless we specify a minimal set of p...
