The search for invariant subspaces is one of the most important themes in linear algebra. The reason is simple: as we will see below, the matrix representation of an operator with respect to a basis is greatly simplified (i.e., it becomes block-triangular or block-diagonal) if some of ...

Hi all, I am a beginner in Linear Algebra. I am solving problems on vector spaces and subspaces from the book Introduction to Linear Algebra by Gilbert Strang. I have come across the following question: Suppose P is a plane through (0,0,0) and L is a line through (0,0,0). The ...
2016, Elementary Linear Algebra (Fifth Edition)Stephen Andrilli, David Hecker Chapter Finite Dimensional Vector Spaces 4.2 Subspaces When a vector space is a subset of a known vector space and has the same operations, it becomes easier to handle. These subsets, called subspaces, also provide addi...
What Are Vector Subspaces in Linear Algebra? Hi guys. I need some help with question #5 from my assignment. If someone can just tell me how to get the question started, it would be great. Thanks :smile: http://img34.exs.cx/img34/8320/algebra1.jpg ...
For any scalar $${\\xi \\in \\mathbb{F}}$$ , there is a characterization of any linear map L : Alg $${\\mathcal{L} ightarrow {m Alg} {\\mathcal{L}}}$$ satisfying $${L([A,B]_\\xi) = [L(A),B]_\\xi + [A,L(B)]_\\xi}$$ for any $${A, B \\in{m Alg...
