Automatic classification of automorphisms of lower-dimensional Lie algebras
C. Wafo Soh
We implement two algorithms in MATHEMATICA for classifying automorphisms of lower-dimensional non-commutative Lie algebras. The first algorithm is a brute-force approach whereas th…

Symbolic Solutions of Simultaneous First-order PDEs in One Unknown
Célestin Wafo Soh
We propose and implement an algorithm for solving an overdetermined system of partial differential equations in one unknown. Our approach relies on Bour-Mayer method to determine c…

iso-spectral Euler-Bernoulli beams à la Sophus Lie
C. Wafo Soh
We obtain iso-spectral Euler-Bernoulli beams by using factorization and Lie symmetry techniques. The canonical Euler-Bernoulli beam operator is factorized as the product of a secon…
