Abstract
We introduce a sharp trace Tr#

and a sharp determinant Det#(l−z

) for an algebra of operators

acting on functions of bounded variation on the real line. We show that the zeroes of the sharp determinant describe the discrete spectrum of

. The relationship with weighted zeta functions of interval maps and Milnor-Thurston kneading determinants is explained. This yields a result on convergence of the discrete spectrum of approximated operators.
