It has been widely acknowledged that the choice of Japanese demonstratives (the distal a-series, the medial so-series, and the proximal ko-series) in their anaphoric use is regulated by the rules concerned with the interlocutors’ knowledge of the referent. In crosslinguistic discussions of anaphoric demonstratives, on the other hand, the effect of the interlocutors’ knowledge of the referent ha...

Let 3 ≤ k < n/2. We prove the analogue of the Erdős-Ko-Rado theorem for the random k-uniform hypergraph Gk(n, p) when k < (n/2)1/3; that is, we show that with probability tending to 1 as n → ∞, the maximum size of an intersecting subfamily of Gk(n, p) is the size of a maximum trivial family. The analogue of the Erdős-Ko-Rado theorem does not hold for all p when k À n1/3. We give quite precise r...

Erdős-Ko-Rado sets in finite classical polar spaces are sets of generators that intersect pairwise non-trivially. We improve the known upper bound for Erdős-Ko-Rado sets in H(2d + 1, q) for d > 2 and d even from approximately q +d to q 2+1.

2. An important concept will be that of a component of a family 2F. Consider the equivalence relation on / generated by the relation R defined by: i'RV'o Fv n Fr T* 0 . Let /* be any equivalence class. Then &* = is, by definition, a component of $F. If Fv and Fv> are in different components, then jp., n Fv> = 0 . This means that 0? has a transversal if and only if every component of ...

We present a descent style, Bockstein spectral sequence computing Ext over the motivic Steenrod algebra over R and related sub-Hopf algebras. We demonstrate the workings of this spectral sequence in several examples, providing motivic analogues to the classical computations related to BP 〈n〉 and ko.

Document Summary) In recent research on service quality it has been argued that the relationship between perceived service quality and service loyalty is an issue which requires conceptual and empirical elaboration through replication and extension of current knowledge. A study focuses on the refinement of a scale for measuring service loyalty dimensions and the relationships between dimensions...

Each year, the American Cancer Society (ACS) publishes a report summarizing its recommendations for early cancer detection, data and trends in cancer screening rates, and select issues related to cancer screening. In 2008, the ACS, the American Gastroenterological Association, the American College of Gastroenterology, the Society for Gastrointestinal Endoscopy, and the American College of Radio...

contributions to Catalan's classical problem to show that 8,9 is the only pair of consecutive positive integers which are both perfect powers. The work of Professor Ko and the related work by others show that there is just one mathematical world and that there are no borders in this world. For any positive integer n let P (n); !(n); (n) denote the greatest prime factor of n, the number of disti...

Motivated by the Frankl’s results in [11] (“Multiply-intersecting families,” J. Combin. Theory (B) 1991), we consider some problems concerning the maximum size of multiply-intersecting families with additional conditions. Among other results, we show the following version of the Erdős–Ko–Rado theorem: for all r ≥ 8 and 1≤ t ≤ 2r+1−3r−1 there exist positive constants ε and n0 such that if n > n0...
