The (Self-Similar, Variational) Rolling Stones
Abstract
The interplay between variational functionals and the Brunn-Minkowski Theory is a well-established phenomenon widely investigated in the last thirty years. In this work, we prove the existence of solutions to the even logarithmic Minkowski problems arising from variational functionals, such as the first eigenvalue of the Laplacian and the torsional rigidity. In particular, we lay down a blueprint showing that the same result holds for more generic functionals by adapting the volume case from B\"or\"oczky, Lutwak, Yang, and Zhang. We show how these results imply the existence of self-similar solutions to variational flow problems \`a la Firey's worn stone problem.

Comments
16-18 pages; added connection to Firey's worn stones (v2) and clarifying comments concerning the scope of the results (v3). We greatly improved the presentation of the construction of set-dependent Borel measures (v4). Added IMRN DOI and fixed some grammar typos (v5)
