【2.A.2】【2.B】线性独立(linear independence)、张成组(spanning list)和基(basis) 这是一篇高潮迭起的文章,我们即将开阔眼界、提升思维和掌握工具。 线性独立(linear independent) V中一列矢量v1,v2...vn的线性组合a1v1+a2v2+...+anvn=0只有在a1=a2=...=an=0时才成立,就说矢量v1,v2...vn线性...
We answer a number of open problems in frame theory concerning the decomposition of frames into linearly independent and/or spanning sets. We prove that Parseval frames with norms bounded away from 1 can be de-composed into a number of sets whose complements are spanning, where the number of ...
In particular, it provides construction procedures for these special sets of vectors that were not previously mentioned in the literature. It also proves that invertible linear transformations preserve positive independence and the positive spanning property. Moreover, this article introduces the notion of...
Do two empty sets intersect? Explain your answer. Where is the principal log branch not analytic? Determine whether or not the set \{(x,y) | 1\lt |x| \lt 3 \} is a) open, b) connected, and c) simply-connected. How can the sets be pairwise independent but not mutually independe...

Given the limitations imposed by the data sets and specific model outputs required by our research objectives, relaxing some of these assumptions was sometimes necessary. The assumptions are as follows: (1) closure: occupancy status at each site does not change over the sampling period; (2) ...
