On the Blocks of Interpoint Distances
We study the blocks of interpoint distances, their distributions, correlations, independence and the homogeneity of their total variances. We discuss the exact and asymptotic distribution of the interpoint distances and their average under three models and provide connections between the correlation of interpoint distances with their vector correlation and test of sphericity. We discuss testing...
متن کاملDistances forbidden bY two - colorings of Q 3 and A ,
Chow, T., Distances forbidden by two-colorings of Q3 and A,, Discrete Mathematics 115 (1993) 95-102. For X = Q3 or A, (where A, is the set of points in Q” whose coordinates have odd denominators), we characterize all sets of distances D c R + with the following property: there exists some two-coloring of X such that, for all d ED, no two points in X that arc a distance d apart are the same colo...
متن کاملConstructing new q-ary quantum MDS codes with distances bigger than q/2 from generator matrices
The construction of quantum error-correcting codes has been an active field of quantum information theory since the publication of [1, 2, 3]. It is becoming more and more difficult to construct some new quantum MDS codes with large minimum distance. In this paper, based on the approach developed in the paper [4], we construct several new classes of quantum MDS codes. The quantum MDS codes exhib...
متن کاملNew q-ary quantum MDS codes with distances bigger than \(\frac{q}{2}\)
Constructions of quantum MDS codes have been studied by many authors. We refer to the table in page 1482 of [3] for known constructions. However there have been constructed only a few q-ary quantum MDS [[n, n−2d+2, d]]q codes with minimum distances d > q 2 for sparse lengths n > q + 1. In the case n = q 2 −1 m where m|q + 1 or m|q − 1 there are complete results. In the case n = q 2 −1 m while m...
متن کاملON Q-BITOPOLOGICAL SPACES
We study here $T_{0}$-$Q$-bitopological spaces and sober $Q$-bitopological spaces and their relationship with two particular Sierpinski objects in the category of $Q$-bitopological spaces. The epireflective hulls of both these Sierpinski objects in the category of $Q$-bitopological spaces turn out to be the category of $T_0$-$Q$-bitopological spaces. We show that only one of these Sierpinski ob...
