Matchings and Perfect Matchings
2009As a young branch of mathematics, Graph Theory has experienced the explosion growth as the same phenomenon that has been taking place in computing science and communication networking. In the mean time, there are many new terminologies and knowledge accumulated in the process. So there are often more than one names or notions defined for a same entity.

On an obstruction for perfect matchings
Combinatorica, 1984\textit{K. Steffens} [Can. J. Math. 29, 165-168 (1976; Zbl 0324.05122)] proved a necessary and sufficient condition for the existence of perfect matchings in countable graphs. He presented a substructure (called ''compressed set'') which obstructs perfect matchings in any graph, and proved that in the countable case this is the only possible ...

Groups and Automata: A Perfect Match
2012We present a personal perspective, inspired by our own research experience, of the interaction between group theory and automata theory: from Benois' Theorem to Stallings' automata, from hyperbolic to automatic groups, not forgetting the exotic automaton groups.

The 'S-complex' asteroids are not easily identified as the source of the most common meteorites reaching Earth. Their relationship might be disguised, however, by the effects of space weathering.

In this chapter, Joan Acker’s concept of gendered work ideals is used to understand the cultural clashes in transnational collaboration between Swedish and Indian firms. Interviews in two firms show that Indian employees collaborating with Sweden meet with conflicting ideals which they find difficult to realize, because of the differences between the ...
