Wim H. Hesselinklutions with small amplitudes are unstable..When the Floquet exponents at criticality are complex and rationally independent of the fixed frequency, the solution of the spectral problem is quasi-periodic. The formal construction then gives the natural frequency of the bifurcating solution as a power

Towards a calculus of data refinement,In this paper we lay a foundation for a calculus of data refinement. We introduce the concept of conditional data refinement which enables us to incorporate contextual information in a refinement step. We give a number of its properties and show in several examples how data refinement can be used in practice.
