We exhibit that the radial eigenfunctions of a 2D-harmonic oscillator 2DHO may be Ε½ . regarded as 1D-harmonic oscillator 1DHO matrix elements. From this simple fact and using as a starting point the ladder operators a " for 1DHO, we obtain ladder operators for 2DHO. Furthermore, by using the relatio

For high wave numbers, the Helmholtz equation su!ers the so-called &pollution e!ect'. This e!ect is directly related to the dispersion. A method to measure the dispersion on any numerical method related to the classical Galerkin FEM is presented. This method does not require to compute the numerical
