摘要

We study minimizing cones in the Alt-Phillips problem for when the exponent \(\gamma \) γ is for close to 1. For when \(\gamma \) γ converges to 1, we show that the cones concentrate around symmetric solutions to the classical obstacle problem. To be precise, the limiting profiles are radial in a subspace and invariant in directions perpendicular to that subspace.
