We examine semantic properties of Korean plural expressions and how they are related to genericity and definiteness. First of all, Korean plural expressions provide a strong evidence for the plurality theory which discerns between the two sorts of plural individuals such as sum and group. Sum and group are clearly distinguished by morphological markers in Korean i.e., 'tul-plurals and ${\phi}$-plurals correspond to sum and group interpretations respectively. Second, the treatment of Korean bare singulars(=${\phi}$-plurals) as group accounts for why Korean generic NPs prefer bare singulars to bare plurals. Generic NPs refer to kind, and kind is a special group derived from supremum, therefore both generic NPs and bare singulars refer to group, and generic NPs are realized as bare singulars rather than bare plurals in Korean. Finally, in Korean, plurality and definiteness have little effect on each other although some connection between them has often been reported in the literature.

Since countability is a grammatical notion, the distinction between count and mass nouns may not reflect countability in the real world. Based on this, Chierchia (1998a; 1998b) provides a typological study of plurality and genericity, which does not account for countability in Korean. Nemoto (2005) revises Chierchia's analysis to deal with count and mass nouns in Korean and Japanese. This study discusses problems with the previous analyses and proposes that the semantic feature of humanness is the main criterion for countability in Korean.

We introduce here notions of chain recurrent sets, attractors and its basins for general dynamical systems and prove important properties including (i) the chain recurrent set CR(f) of f on a metric space (X, d) is the complement of the union of sets B(A) -A as A varies over the collection of attractors and (ii) genericity of general dynamical systems.

We study the genericity of the first weak inverse shadowing property and the second weak inverse shadowing property in the space of homeomorphisms on a compact metric space, and show that every shift homeomorphism does not have the first weak inverse shadowing property but it has the second weak inverse shadowing property.

In this paper we introduce the notions of strict persistence and weakly strict persistence which are stronger than those of persistence and weak persistence, respectively, and study their relations with shadowing property. In particular, we show that the weakly strict persistence and the weak inverse shadowing property are locally generic in Z(M).

Smale [16] posed the following question; is having an attracting periodic orbit a generic property for diffeomorphisms of two-sphere $S^2\ulcorner$(A generic property of $f \in Diff(M)$ is one that is true for a Baire set in Diff(M)). Mane[5] and Plykin[13] had an positive answer for Axiom A diffeomorphisms of $S^2$. To explain our theorem, we begin by briefly recalling stability conjecture posed by palis and smale.

Stroik (1992, 1995, 1999) argues for the syntactic approach to English middles. His argumentation is heavily dependent upon the occurrence of a for-phrase in middles. However, many native speakers of English judge middles containing a for-phrase awkward or at best marginal. In addition, some other adverbials show a trait of a very similar nature. These two observational facts seem to justify the Genericity Constraint on Middles (=GCM). Yet a third observational fact that middles in the past tense can be sporadic nullifies GCM. In the present article, based upon several pieces of evidence, I show that the subject of the middle is a topic. In addition, it is argued that the Topical Subject Constraint on Middles can explain away the three observational facts.

In this article, we focus on certain dynamic phenomena in volume-preserving manifolds. Let $M$ be a compact manifold with a volume form ${\omega}$ and $f:M{\rightarrow}M$ be a diffeomorphism of class $\mathcal{C}^1$ that preserves ${\omega}$. In this paper, we do not assume $f$ is $\mathcal{C}^1$-generic. We prove that $f$ satisfies the chain transitivity and we also show that, on $M$, the $\mathcal{C}^1$-stable shadowability is equivalent to the hyperbolicity.
