Often labelled by a lambda, their constituent set is referred to as the spectrum, and are solutions to the characteristic polynomial.
Capable of being bounded by Gresgorin discs, Jacques Strum first studied these numbers in a general setting. Often labelled by a lambda, their constituent set is referred to as the spectrum, and are solutions to the characteristic polynomial. Their sum equals the matrix's trace, and their product equals the matrix's determinant. FTP, what are these "values" which for some value of x and matrix A fulfill the equation A times x equals lambda x?
