In an important step forward Maskin (1977) showed that two properties −Monotonicity and No Veto Power − form a sufficient condition for Nash implementation when conjoinet. In contrast to the vast literature that followed, this characterization has two big advantages: First, it is often easy to verify, and second, it has an elegant and simple interpretation. However, there does not exist a simil...

The fundamental question in both basic and applied population biology of whether a species will increase in numbers is often investigated by finding the population growth rate as the largest eigenvalue of a deterministic matrix model. For a population classified only by age, and not stage or size, a simpler biologically interpretable condition can be used, namely whether R0, the mean number of ...

This paper is concerned with constraints on the interpretation of pronominal anaphora, in particular Condition B effects. It aims to contribute to a particular approach, initiated by Reinhart (1983) and further developed by Heim (1998), Fox (2000), Büring (2005b), Reinhart (2006), and Reuland (2008). It proposes a modification of Reinhart’s Interface Rule, and argues that the resulting theory c...

in this paper, we aresupposed to introduce the definitions of n-fold commutative, andimplicative hyper k-ideals. these definitions are thegeneralizations of the definitions of commutative, andimplicative hyper k-ideals, respectively, which have been definedin [12]. then we obtain some related results. in particular wedetermine the relationships between n-fold implicative hyperk-ideal and n-fold...
