A family of sets is t-intersecting if any two sets from the family contain at least t common elements. Given a t-intersecting family of r-sets from an n-set, how many distinct sets of size k can occur as pairwise intersections of its members? We prove an asymptotic upper bound on this number that can always be achieved. This result can be seen as a generalization of the Erdős-Ko-Rado theorem.
In this paper we study a question related to the classical Erdős–Ko–Rado theorem, which states that any family of k-element subsets of the set [n] = {1, . . . , n} in which any two sets intersect, has cardinality at most (︀ n−1 k−1 )︀ . We say that two non-empty families are A,B ⊂ (︀[n] k )︀ are s-cross-intersecting, if for any A ∈ A, B ∈ B we have |A ∩ B| ≥ s. In this paper we determine the ma...
We show that Ossa’s theorem splitting ku∧BV for elementary abelian groups V follows from general facts about ku∧BZ/2 and Adams covers. For completeness, we also provide the analogous results for ko ∧BV .
in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
this thesis attempts to study the representations of the third-world intellectuals in three fictional works by the british-educated trinidadian nobel-winner v. s. naipaul: the mimic men, a bend in the river, and magic seeds. the first one recounts the story of ralph singh’s sense of alienation, his experiences as a colonial politician, and his struggle to give order to his disorderly world thro...
Two set partitions of an n-set are said to t-intersect if they have t classes in common. A k-partition is a set partition with k classes and a k-partition is said to be uniform if every class has the same cardinality c = n/k. In this paper, we prove a higher order generalization of the Erdős-Ko-Rado theorem for systems of pairwise t-intersecting uniform k-partitions of an n-set. We prove that f...
We prove a p-part extension of the Erdős-Ko-Rado Theorem and suggest several related open problems. For the basic case of two parts we describe two proofs, a combinatorial one and a spectral one.
We describe the space of E∞ spin orientations of KO and the space of E∞ string orientations of tmf.
