Bernoulli map: oops uniform notation w/ rest of article
Line 111:
It is the fact that the eigenvalues <math>k^{-m}<1</math> that marks this as a dissipative system: for a non-dissipative [[measure-preserving dynamical system]], the eigenvalues of the transfer operator lie on the unit circle.
 
More generally, this operator also has a continuous spectrum: the Hurwitz zeta function <math>\zeta(s,x)</math> is also an eigenvector, with eigenvalue <math>k^{-s}</math>. Note that the Bernoulli polynomials arise as limiting cases of the Hurwitz zeta for integer values of ''-s''.
