Classification of solutions of an equation related to a conformal log Sobolev inequality

Rupert L. Frank, Tobias König, Hanli Tang

We classify all finite energy solutions of an equation which arises as the Euler--Lagrange equation of a conformally invariant logarithmic Sobolev inequality on the sphere due to B…

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

Rupert Frank, Tobias König, Hynek Kovarik

For dimensions , we consider the Brézis-Nirenberg variational problem of finding \[ S(εV) := \inf_{0\not\equiv u\in H^1_0(Ω)} \frac{\int_Ω|\nabla u|^2 \, dx +ε\int_ΩV\, |…

Energy asymptotics in the three-dimensional Brezis--Nirenberg problem

Rupert L. Frank, Tobias König, Hynek Kovarik

For a bounded open set we consider the minimization problem $$ S(a+εV) = \inf_{0\not\equiv u\in H^1_0(Ω)} \frac{\int_Ω(|\nabla u|^2+ (a+εV) |u|^2)\,dx}{(\int_…

Liquid Drop Model for Nuclear Matter in the Dilute Limit

Lukas Emmert, Rupert L. Frank, Tobias König

We consider the liquid drop model for nuclei interacting with a neutralizing homogeneous background of electrons. The regime we are interested in is when the fraction between the e…
