we say that a finite group $g$ is conjugacy expansive if for anynormal subset $s$ and any conjugacy class $c$ of $g$ the normalset $sc$ consists of at least as many conjugacy classes of $g$ as$s$ does. halasi, mar'oti, sidki, bezerra have shown that a groupis conjugacy expansive if and only if it is a direct product ofconjugacy expansive simple or abelian groups.by considering a character analo...

the aim of this note is to characterize the finite groups in which all non-linear irreducible characters have distinct zero entries number.

Each homogeneous space of a quasigroup affords a representation of the BoseMesner algebra of the association scheme given by the action of the multiplication group. The homogeneous space is said to be faithful if the corresponding representation of the Bose-Mesner algebra is faithful. In the group case, this definition agrees with the usual concept of faithfulness for transitive permutation rep...

This study investigates how Seoul Korean-speaking children and adults use pitchand duration-related phonetic cues to mark focus. It was found that to distinguish focus from non-focus, the adults used both the pitchand duration-related cues, but the children used only the duration-related cues to distinguish focus from post-focus. Further, neither the adults nor the children distinguish narrow f...

This paper deals with an aspectual classification of Korean and Japanese verbs based on Vendler (1967). Both of Korean and Japanese verbs are classified into 12 distinctive aspectual categories by their restrictions on time adverbials, progressive tenses and logical entailments. A well-established aspectual verb classes provide us not only with a better understanding of both languages, but also...
