摘要

正交阵列作为组合设计理论和实验设计理论领域的一个重要研究课题，在统计学、计算机科学、编码理论和密码学中有着广泛的应用。本文介绍了非对称正交阵列的三种构造，包括并列、伽罗瓦域上的生成矩阵和混合差分矩阵。随后，得到了强度 t≥3 的许多新的非对称正交阵列无穷族。此外，还得到了一些新的具有混合水平的大集正交阵列无穷族。

New results on asymmetric orthogonal arrays with strength t ≥ 3

The orthogonal array holds significant importance as a research topic within the realms of combinatorial design theory and experimental design theory, with widespread applications in statistics, computer science, coding theory and cryptography. This paper presents three constructions for asymmetric orthogonal arrays including juxtaposition, generator matrices over Galois fields and mixed difference matrices. Subsequently, many new infinite families of asymmetric orthogonal arrays with strength $t \geq 3$ are obtained. Furthermore, some new infinite families of large sets of orthogonal arrays with mixed levels are also obtained.

期刊介绍： Discrete Mathematics provides a common forum for significant research in many areas of discrete mathematics and combinatorics. Among the fields covered by Discrete Mathematics are graph and hypergraph theory, enumeration, coding theory, block designs, the combinatorics of partially ordered sets, extremal set theory, matroid theory, algebraic combinatorics, discrete geometry, matrices, and discrete probability theory. Items in the journal include research articles (Contributions or Notes, depending on length) and survey/expository articles (Perspectives). Efforts are made to process the submission of Notes (short articles) quickly. The Perspectives section features expository articles accessible to a broad audience that cast new light or present unifying points of view on well-known or insufficiently-known topics.
