Fundamentals Of Linear Algebra Katsumi Nomizu Pdf 17

However, in practice, there will be no selfadjoint endomorphisms or simple subspaces, so we have to pass to the semisimple quotient. This is what makes this work a bit more difficult, and there is less flexibility. However, since every linear map is represented by a matrix, even a semisimple vector space can be handled by looking at the underlying matrix algebra. There are several definitions of semisimplicity; we will take the definition of Morita equivalence, namely that the algebra of $1 imes 1$ matrices is isomorphic to the algebra of endomorphisms of the algebra of $2 imes 2$ matrices. In general, a vector space is semisimple if the only linear maps it can implement are given by matrices of $0$s and $1$s.

A commutative algebra $\rho$ is called factor-algebra of the commutative algebra $\Sigma$ if there exists an algebra isomorphism from $\rho$ to a subalgebra of $\Sigma$ which maps $\rho$ onto $\Sigma$. This means that there is a generalization of the construction of the symmetric algebra of a vector space. In particular, we associate to $\rho$ the same vector space as before, i.e. the linear subspace $\rho \otimes \Bbb R$ of $\rho \otimes \Bbb C$. But instead of $n$ commuting squares of vector spaces, we have commutative squares of rings. The problem is that we need a set of objects that is closed under these square operations. If we use the set of all matrices, we will have problems with the product of $m \times n$ matrices and $n \times p$ matrices, since the product of $m \times n$ matrices with $n \times p$ matrices is not a matrix in general.

Maybe I can answer your question a little. Linear algebra has its origins in the 19th century, beginning with the case of complex numbers. After that we have the algebra of complex numbers, then the algebra of $n$-dimensional complex vector spaces. At a later stage (in the 20th century) we have spaces of functions, spaces of operators, spaces of differential equations, spaces of partial differential equations etc.

If you have all the background in functional analysis, it should be easy to understand the theory of linear transformations. One way or another the subject can be treated as a functional analysis of the sequence space, usually ${\mathbb{R}}^n$ or ${\mathbb{C}}^n$. For the treatment of the decomposition theorem there is http://math.berkeley.edu/~theo/papers/decomp.pdf , and of the Jordan theorem, there is http://math.berkeley.edu/~theo/papers/nodecomp.pdf . It’s all explained here, as well as basic linear algebra. I strongly suggest that you take a look at these, and from the viewpoint of functional analysis, it is very understandable.
Matrices, linear transformations, Jordan form, eigenvalues and eigenvectors are common in a much larger context: functional analysis. There are several books on these topics. For instance you might want to look at Functional Analysis and Many Particle Systems , by E. Hebey and Functional Analysis , by R. Adams. In some places the linear algebra content is quite complicated, and in other places it is very simple. If you are just looking for a way of thinking about linear algebra in terms of (finite dimensional) vector spaces of functions, the analysis texts are great.
i have three month course (master) of math subjects. in algebra course first course i start with categorical approach, linear algebra linear space, groups, rings, homo and isotorn groups… which i have studied on my own ( not knowing it in noe science class, just dint know it ) Then in another course i start with main stream algebra,i.e., polynomial, function etc. i know the above all thing very well but the thing that i dont know is how to start studying theory of linear equation. i went through many books but as a beginner i found the theory very intresting. but i am having problem which theory to start. can you please help me, i want to make good foundation for my underatanding the theory of linear equation. thank you in advance.
