复等角紧框架与擦除

Complex Equiangular Tight Frames and Erasures

Thomas Hoffman, James Solazzo

摘要:

在本文中,我们证明了真实的和复杂的等角紧框架(ETF)之间的擦除有明显的差异。例如,我们证明了存在任意大的非平凡的复杂等角紧框架,这是强大的对三个擦除,这样的框架来自一个独特的类复杂的ETF。此外,我们将\cite{BP}中的某些结果推广到复向量空间,并证明了其他关于真实ETF的结果对复ETF是无效的。

英文摘要:

In this paper we demonstrate that there are distinct differences between real and complex equiangular tight frames (ETFs) with regards to erasures. For example, we prove that there exist arbitrarily large non-trivial complex equiangular tight frames which are robust against three erasures, and that such frames come from a unique class of complex ETFs. In addition, we extend certain results in \cite{BP} to complex vector spaces as well as show that other results regarding real ETFs are not valid for complex ETFs.
