Compensated integrability on tori; a priori estimate for space-periodic gas flows by Serre, Denis

“…We apply our abstract results in two contexts, for which $k=1$ is associated with a time variable, while $m=d$ is a space dimension. On the one hand to $d$-dimensional inviscid gas dynamics, governed by the Euler equations, when the initial data is space-periodic; we obtain an a priori space-time estimate of our beloved quantity $\rho ^{\frac{1}{d}}p$. …”
