Fractional H-measures and transport property
Microlocal defect functionals (H-measures, H- distributions, semiclassical measures etc.) are objects which determine, in some sense, the lack of strong compactness for weakly convergent Lp sequences. H-measures are suitable to treat problems where all partial derivatives are of the same order [4]. Recently, parabolic H- measures are introduced in order to treat 1:2 ratio between orders of partial derivatives [1], and also fractional H-measures which treat arbitrary ratios [2, 3]. We generalise Second commutation lemmas introduced in [1] and [4] to fractional Hmeasures, from which we are able to derive the propagation principle for the following fourth order partial differential equation: iu_t + (a(x)u_xx)_xx = f.
