A general study of minimal surfaces of the Riemannian product of two spheres S^2xS^2 is tackled.

This correspondence also allows us to link minimal surfaces in S^3 and in the Riem…

We study properly embedded and immersed p(pseudohermitian)-minimal surfaces in the 3-dimensional Heisenberg group. From the recent work of Cheng, Hwang, Malchiodi, and Yang, we learn that such surfaces must be ruled surfaces. There are two types of such surfaces: band type and annulus type according to their topology. …

We prove a general fusion theorem for complete orientable minimal surfaces in R3\mathbb{R}^3 with finite total curvature. As a consequence, complete orientable minimal surfaces of weak finite total curvature with exotic geometry are produced. More specifically, universal surfaces (i.e., surfaces from which all minimal …
