Abstract:
We report recent work on the asymptotic behavior of extremal functions for the Sobolev embedding from $H^1$ into $L^p$ as $p \to 2$. This gives a precise convergence result of the ground states of the scalar field equation, and in turn yields a direct proof of the logarithmic Sobolev inequality by passing limit in the Sobolev embedding.
