一般来说,具有实系数的多项式的复根,如果以它们的重复次数计数,与多项式的次数一样多。这一事实非常重要,以至于被高调宣扬为代数基本定理( the fundamental theorem of algebra)。但正如我们在多项式F2中已经注意到的,多项式可能没有任何实根。 我们几乎准备好看到一个真正伟大的新定理,但首先我们想回应一些读者肯定在...
Theorem 8.1: Let V be a linear vector space over the scalars F. (Here we will typically only use F=R or F=C). A subset W⊂V is a linear vector space, i.e. a subspace, if and only if W satisfies the following three conditions: The zero vector 0∈W. If v1∈W and v2∈...
One of the most important theorems in Linear Algebra is Cayley-Hamilton theorem: q(T) =0. We know q(T) = 0 and deg q = n. Is it possible we find another polynomial p(t) for which p(T) = 0 and deg p <= deg q? The answer is yes. Such polynomial p is called minimal ...
Remark:A nonempty collection A of matrices is called an algebra (of matrices) if A is closed under the operations of matrix addition, scalar multiplication, and matrix multiplication. Clearly, the square matrices with a given order form an algebra of matrices, but so do the scalar, diagonal, ...
