WebMar 24, 2024 · Eigenvalues are a special set of scalars associated with a linear system of equations (i.e., a matrix equation ) that are sometimes also known as characteristic roots, characteristic values (Hoffman and Kunze 1971), proper values, or latent roots (Marcus and Minc 1988, p. 144). WebThe constant coefficient of the characteristic polynomial = determinant of $A.$ A non-zero determinant implies the matrix is invertible. – user2468 Jul 3, 2012 at 18:38 The invertibility property does not depend on the base field. So if a matrix with real coefficients has a complex inverse, this inverse is in fact real. – Lierre
