Circular External Difference Families: Construction and Non-Existence
Huawei Wu, Jing Yang, Keqin Feng
The circular external difference family and its strong version, which themselves are of independent combinatorial interest, were proposed as variants of the difference family to co…
Arithmetic crosscorrelation of binary -sequences with coprime periods
Xiaoyan Jing, Keqin Feng
The arithmetic crosscorrelation of binary -sequences with coprime periods and \ () is determined. The result shows that the absolute valu…
Constructions of -uniform states in heterogeneous systems
Keqin Feng, Lingfei Jin, Chaoping Xing +1
A pure quantum state of parties associated with the Hilbert space $\CC^{d_1}\otimes \CC^{d_2}\otimes\cdots\otimes \CC^{d_n}$ is called -uniform if all the reductions to -…
Optimal Combinatorial Neural Codes with Matched Metric : Characterization and Constructions
Aixian Zhang, Xiaoyan Jin, Keqin Feng
Based on the theoretical neuroscience, G. Cotardo and A. Ravagnavi in \cite{CR} introduced a kind of asymmetric binary codes called combinatorial neural codes (CN codes for short),…
Cyclotomic Construction of Strong External Difference Families in Finite Fields
Jiejing Wen, Minghui Yang, Fangwei Fu +1
Strong external difference family (SEDF) and its generalizations GSEDF, BGSEDF in a finite abelian group are combinatorial designs raised by Paterson and Stinson [7] in 2016 an…
The -Strong External Difference Family with Exists
Jiejing Wen, Minghui Yang, Keqin Feng
The notion of strong external difference family (SEDF) in a finite abelian group is raised by M. B. Paterson and D. R. Stinson [5] in 2016 and motivated by its application…
