It is equivalent to "A complex number ? is called an eigenvalue
of T if Tx = ?x for some nonzero x"

studying linear algebra at the university. Years later I found

This is a great paper.As a counterpoint, one place where
determinants are incredibly useful is in Hartree-Fock theory, where
they effective encode the Pauli exclusion principle (or anti-
symmetry requirements) of atomic
