We emphasize that V˙q,σ,θs\documentclass[12pt]{minimal}\usepackage{amsmath}\usepackage{wasysym}\usepackage{amsfonts}\usepackage{amssymb}\usepackage{amsbsy}\usepackage{mathrsfs}\usepackage{upgreek}\setlength{\oddsidemargin}{-69pt}\begin{document}$${\dot{V}}^{s}_{q,\sigma ,\theta }$$\end{document} may be the largest normed space that satisfies the logarithmic interpolation inequality.
