Determinant and characteristic polynomial
WebIgor Konovalov. 10 years ago. To find the eigenvalues you have to find a characteristic polynomial P which you then have to set equal to zero. So in this case P is equal to (λ-5) (λ+1). Set this to zero and solve for λ. So you get λ-5=0 which gives λ=5 and λ+1=0 which gives λ= -1. 1 comment. Webcharacteristic polynomial (as in [9, chap. 7]) or make use of known properties of the characteristic polynomial and determinant for matrices in studying the general charac …

WebThere is only finitely many Jones polynomial equivalence classless of a given determinant as a result of the main theorem. The first result follows since there is only finitely many positive integers less than or equal this determinant. The second result follows directly since the graded Euler characteristic of the Khovanov homology is Webminant. The reason is that the characteristic polynomial and so the eigenvalues only need the trace and determinant. A two dimensional discrete dynamical system has …
