Hill's method is a method for the computation of spectra of
linear operators. The method is ideally suited for spectra of operators with
periodic coefficients in 1,2, or 3 dimensions. Further, the method is easily
extended to problems defined on the whole real line, plane or space. The method
is spectrally convergent due to the use of Fourier series or transforms.
Incorporating Floquet theory allows for the computation of the entire spectrum,
as opposed to a few elements of it.
SpectrUW (pronounced "Spectrum") is a Java-based application that uses Hill's
method as a computational engine. The computations are done in Maple or
Mathematica, which needs to be available on the user's machine. The user only
interacts with the Java interface, never directly with Maple or Mathematica.
SpectrUW is freeware, but we ask that users do acknowledge its use in
scientific publications. The software can be acknowledged by a reference to
either one of the first two papers listed
here.
The current version of SpectrUW (2.0) supports the following:
