Trees and forests,r free, trees. It is shown how to build up trees from the tree with a single vertex, using the beta-product and the B+ operation, together with a prefix (Polish) operator. Formal linear combinations of forests are introduced as the “forest space” and, as an application, the enumeration of trees is s

B-series and Algebraic Analysis,ings. One mapping would be the exact flow through a specified time step and the other would be a numerical scheme, such as a Runge–Kutta method. The B-series approach to questions like this is to write the Taylor expansions of the two mappings in a special way, in terms of “elementary differentials”

,B-series and Runge–Kutta methods,ting there is no interest in numerical methods which are applicable only to scalar problems and, above order 4, an analysis based on B-series is more appropriate. Even for order 5 there exist scalar methods with reduced order when applied to non-scalar problems. Explicit methods to order 5 are deriv
