WebRayleigh’s inﬂection point theorem and Fjortoft’s theorem provide necessary conditions for inviscid temporal instability of a plane parallel ﬂow. Although these theorems have been assumed to hold in the spatial framework also, a rigorous theoretical basis for such an application is not available in the literature.
