Classes for B-series

class pybs.series.Bseries.BseriesRule(arg=None)[source]

Objects of this class are B-series rules for numerical methods.

They treat forests as characters of the Hopf algebra. For other B-series rules use VectorfieldRule or ForestRule.

class pybs.series.Bseries.VectorfieldRule(arg=None)[source]

Objects of this class are B-series rules that correspond to modified equations.

That means they act on forests as infinitesimal characters.

class pybs.series.Bseries.ForestRule(arg=None)[source]

General rule with arbitrary behavior for forest.

Use this if the two others are unsuitable.
