An r-unform n-vertex hypergraph H is said to have the Manickam-Miklós-Singhi (MMS) property if for every assignment of weights to its vertices with nonnegative sum, the number of edges whose total weight is nonnegative is at least the minimum degree of H. In this paper we show that for n > 10r, every r-uniform n-vertex hypergraph with equal codegrees has the MMS property, and the bound on n is ...

The isometry group of a compact n-dimensional hyperbolic man-ifold is known to be finite. We show that for every n ≥ 2, every finite group is realized as the full isometry group of some compact hyperbolic n-manifold. The cases n = 2 and n = 3 have been proven by Greenberg [G] and Ko-jima [K], respectively. Our proof is non constructive: it uses counting results from subgroup growth theory to sh...

Single and multipass two-body and three-body abrasive wear behaviour of various polyaryletherketone composites have been carried out by using a pin-on-disc machine and a rubber wheel abrasion test (RWAT) rig. Abrasive wear studies were conducted under different loads and sliding distances. Comparative wear performance of all the composites at different loads shows that specific wear rate (Ko) o...

The Erdős–Ko–Rado theorem determines the largest μp-measure of an intersecting family of sets. We consider the analogue of this theorem to t-intersecting families (families in which any two sets have at least t elements in common), following Ahlswede and Khachatrian [1, 2]. We present a proof of the μp version of their theorem, which is adapted from the earlier proofs. Due to the simpler nature...

This paper inlroduces the thermal column or the cold neutron guide beam of the 20 MW NBSR at the National Institute of Standards and Technology as a direct k o measurement facility. Measurement of k o at this facility not only produces accurate values, but avoids the additional correction factors needed in other measurement methods. The ko of Sb, Ag and Cr with respect to Sc as monitor have bee...

Let [n]r be the complete r-partite hypergraph with vertex classes of size n. It is an easy exercise to show that every set of more than (k − 1)nr−1 edges in [n]r contains a matching of size k. We conjecture the following rainbow version of this observation: If F1, F2, . . . , Fk ⊆ [n]r are of size larger than (k− 1)nr−1 then there exists a rainbow matching, i.e. a choice of disjoint edges fi ∈ ...

We study the interaction between polynomial space randomness and a fundamental result of analysis, the Lebesgue differentiation theorem. We generalize Ko’s framework for polynomial space computability in R to define weakly pspace-random points, a new variant of polynomial space randomness. We show that the Lebesgue differentiation theorem characterizes weakly pspace random points. That is, a po...
