On changing cofinality of partially ordered sets
It is shown that under GCH every poset preserves its cofinality in any cofinality preserving extension. On the other hand, starting with measurable cardinals, a model with a part...

Adding clubs with square
We present a technique for destroying stationary subsets of P+ using partial square sequences. We combine this method with Gitik's poset for changing the cofinality of a cardi...

Reinforcement learning for DEC-MDPs with changing action sets and partially ordered dependencies
Decentralized Markov decision processes are frequently used to model cooperative multi-agent systems. In this paper, we identify a subclass of general DEC-MDPs that features regul...

Topologically Sorted Skylines for Partially Ordered Domains
The vast majority of work on skyline queries considers totally ordered domains, whereas in many applications some attributes are partially ordered, as for instance, domains of set ...
