论文摘要
在最近的一项调查中,施密特在广义弯曲函数,组不变的Butson Hadamard矩阵和Abelian分裂相对差异集之间编制了等价。我们通过考虑cocyclic而不是严格的组不变的Butson矩阵来建立更广泛的等价网络。该结果有多个应用程序。例如,构建布尔函数的扩展是部分弯曲的函数,包括不存在弯曲函数的情况。
In a recent survey, Schmidt compiled equivalences between generalized bent functions, group invariant Butson Hadamard matrices, and abelian splitting relative difference sets. We establish a broader network of equivalences by considering Butson matrices that are cocyclic rather than strictly group invariant. This result has several applications; for example, to the construction of Boolean functions whose expansions are generalized partially bent functions, including cases where no bent function can exist.
