Nonlinear Periodic Waves in Shallow Waterlate that the obtained expressions are the first two terms of an expanded exact three-dimensional solution to the surface wave equations, which describe the axisymmetrical and the simplest unaxisymmetrical surface waves in shallow water.

Passive Complete Orthonomic Systems of PDEs and Involutive Bases of Polynomial Modules of passive complete orthonomic systems of linear PDEs with constant coefficients into the language of polynomial modules..We will point out some desirable applications which a “good” notion of involutive bases could provide. Unfortunately, these desires turn out to collide and we will discuss the problem of finding a reasonable compromise.

Symmetries of Second- and Third-Order Ordinary Differential Equationsanswer has been obtained by Lie himself. In this article the complete answer for quasilinear equations of order three is given. An important tool is the Janet base representation for the determining system of the symmetries.

Symbolic Methods for the Equivalence Problem for Systems of Implicit Ordinary Differential Equationsfferential equations. The main results of this contribution are two solutions for the equivalence problem, where time derivatives of the input are admitted or not. Apart from the theoretical results we give a sketch for computer algebra based algorithms necessary to solve these problems efficiently.

A Symbolic Procedure for the Diagonalization of Linear PDEs in Accelerated Computational Engineeringal PDEs and creates equivalent differential forms. It turns out that diagonalization automatically distinguishes the variables in the interface- and boundary conditions defined on surfaces normal to the diagonalization direction.
