چکیده
The non-associativity of translations in a quantum system with magnetic field background has received renewed interest association topologically trivial gerbes over $\mathbb{R}^n.$ is described by 3-cocycle the group $\mathbb{R}^n$ values unit circle $S^1.$ space $M$ are classified Dixmier-Douady class which an element $\mathrm{H}^3(M,\mathbb{Z}).$ However, there finer description terms local differential forms degrees $d=0,1,2,3$ and case for $n=3$ 2-form part $B$ non zero divergence. In this paper we study theoretic construction $n$-component fermions on circle. associativity arises when trying to lift translation action 1-particle second quantized system.

Finding Terminology Translations from Non-parallel Corpora
We present a statistical word feature, the Word Relation Matrix, which can be used to find translated pairs of words and terms from non-parallel corpora, across language groups. Online dictionary entries are used as seed words to generate Word Relation Matrices for the unknown words according to correlation measures. Word Relation Matrices are then mapped across the corpora to find translation ...
متن کاملIdentifying Word Translations in Non-Parallel Texts
Common algorithms for sentence and word-alignment allow the automatic identification of word translations from parallel texts. This study suggests that the identification of word translations should also be possible with non-parallel and even unrelated texts. The method proposed is based on the assumption that there is a correlation between the patterns of word cooccurrences in texts of differe...
متن کاملProjective bundles
A projective bundle in PG(2, q) is a collection of q + q + 1 conics that mutually intersect in a single point and hence form another projective plane of order q. The purpose of this paper is to investigate the possibility of partitioning the q5 − q2 conics of PG(2, q) into q2(q − 1) disjoint projective bundles. As a by-product we obtain a multiplier theorem for perfect difference sets that gene...
متن کاملAn Approach to Acquire Word Translations from Non-parallel Texts
Few approaches to extract word translations from non-parallel texts have been proposed so far. Researchers have not been encouraged to work on this topic because extracting information from non-parallel corpora is a difficult task producing poor results. Whereas for parallel texts, word translation extraction can reach about 99%, the accuracy for non-parallel texts has been around 72% up to now...
متن کاملNon-Associative Parallel Prefix Computation
Chen, R.-J. and Y.-S. Hou, Non-associative parallel prefix computation, Information Processing Letters 44 (1992) 91-94. Associativity of a binary operation allows many applications that are not possible with a non-associative binary operation. We propose a method to transform a binary expression into an associative one and present two related applications.
