Group action recognition in soccer videos is a challenging problem due to the difficulties of group action representation and camera motion estimation. This paper presents a novel...
The last dozen years have seen a considerable investment of resources into the research and development of Group Support Systems (GSS) technology. This paper describes how a GSS w...
We study countable universes similar to a free action of a group G. It turns out that this is equivalent to the study of free semi-actions of G, with two universes being transforma...
A symmetric group action on the maximal chains in a finite, ranked poset is local if the adjacent transpositions act in such a way that (i, i + 1) sends each maximal chain either ...
We give a bound on the reconstructibility of an action G X in terms of the reconstructibility of a the action N X, where N is a normal subgroup of G, and the reconstructibility o...
