question:
In a regular Sturm-Liouville problem, the spectrum of these numbers is discrete and semi-infinite. There is a conjecture that, for some positive operator, the zeroes of the Riemann zeta function are in fact this type of value, whose magnitudes can be bound by the size of matrix elements using Schur's inequalities. Symbolized lambda, they can be found by setting to zero the determinant of the matrix minus lambda times the identity matrix or by finding the roots of the* characteristic equation. FTP, what are these values that reveal by how much matrix multiplication changes their corresponding eigenvectors
answer:

Science
