Abstract

A necessary condition for the existence of solutions to the logarithmic Minkowski problem in $\mathbb{R}^2$, which turns to be stronger than the celebrated subspace concentration condition, is given. The sufficient and necessary conditions for the existence of solutions to the logarithmic problem for quadrilaterals, as well as the number of solutions, are fully characterized.

Keywords
