Remark. y- b/2) COS correspond to the same wavenumber rTr/a which is said to have a multiplicity order equal to 2. But for this wavenumber, the homogeneous N e u m a n n problem has two linearly independent solutions. It is also possible to have wavenumbers with a multiplicity order of 3, to which three linearly independent eigenmodes are associated. 2. 26), if it exists, describes the free oscillations of the fluid which fills the domain f~. Such an oscillation is called a resonance mode; the corresponding wavenumber (resp.
