Cayley Hamilton Theorem General Case

Cayley Hamilton Theorem General Case Youtube Since p(d) = 0, we conclude that p(a) = 0. this completes the proof of the cayley hamilton theorem in this special case. step 2: to prove the cayley hamilton theorem in general, we use the fact that any matrix a cn n can be approximated by diagonalizable ma trices. more precisely, given any matrix a cn n, we can find a sequence of matrices {ak. The cayley–hamilton theorem is an immediate consequence of the existence of the jordan normal form for matrices over algebraically closed fields, see jordan normal form § cayley–hamilton theorem. in this section, direct proofs are presented. as the examples above show, obtaining the statement of the cayley–hamilton theorem for an n × n.

Cayley Hamilton Theorem Statement Formula Proof Examples The cayley hamilton theorem. theorem 2.1. for any = (a ij) 2mat n(a) with n 1 and its characteristic polynomial ˜= xn 2 a[x], the matrix ˜( ) 2mat n(a) vanishes. to prove this result, we rst note that when ais a eld then this is the usual cayley hamilton theorem. we will reduce the general case to the special case of elds, or even just. The cayley hamilton theorem forms an important concept that is widely used in the proofs of many theorems in pure mathematics. some of the important applications of this theorem are listed below: the cayley hamilton theorem is used to define vital concepts in control theory such as the controllability of linear systems. Matrix theory: we state and prove the cayley hamilton theorem over a general field f. that is, we show each square matrix with entries in f satisfies its ch. General proofs of the cayley–hamilton theorem • over c all matrices are triangularisable; we have proved the theorem for triangular matrices. • if f 6 c then ca(a) = 0. • for a general proof using adjoint matrices see, for example, t. s. blyth & e. f. robertson, basic linear algebra, p.169 or richard kaye & robert wilson linear algebra.
