This paper explores parallels between minimal surfaces and Einstein manifolds.

problem Understanding Einstein manifolds, which are less studied.
method Synthesizes parallels between minimal surfaces and Einstein four-manifolds.
result Certain Einstein four-manifolds admit a minimal immersion into a higher-dimensional sphere.

We prove that C. Loewner's inequality for the torus is satisfied by all hyperelliptic surfaces X, as well. We first construct the Loewner loops on the (mildly singular) companion tori, locally isometric to X away from the Weierstrass points. The loops are then transplanted to X, and surgered to obtain a Loewner loop on…
