Energy asymptotics in the Brezis–Nirenberg problem: The higher-dimensional case

  • Received: 24 October 2019 Accepted: 23 November 2019 Published: 06 December 2019
  • For dimensions $N \geq 4$, we consider the Brézis-Nirenberg variational problem of finding $ S(\epsilon V) : = \inf\limits_{0\not\equiv u\in H^1_0(\Omega)} \frac{\int_\Omega |\nabla u|^2\, dx +\epsilon \int_\Omega V\, |u|^2\, dx}{\left(\int_\Omega |u|^q \, dx \right)^{2/q}}, $ where $q = \frac{2N}{N-2}$ is the critical Sobolev exponent, $\Omega \subset \mathbb{R}^N$ is a bounded open set and $V:\overline{\Omega}\to \mathbb{R}$ is a continuous function. We compute the asymptotics of $S(0) - S(\epsilon V)$ to leading order as $\epsilon \to 0+$. We give a precise description of the blow-up profile of (almost) minimizing sequences and, in particular, we characterize the concentration points as being extrema of a quotient involving the Robin function. This complements the results from our recent paper in the case $N = 3$.
