In this paper, we study some basic geometric properties of pseudohermitian submanifolds of the Heisenberg groups. In particular, we obtain the uniqueness and ex
New types of hypersurface flows have been introduced recently with goalsto establish isoperimetric type inequalities in geometry. These flows serve as efficient
Non-local equations cannot be treated using classical ODE theorems. Nev-ertheless, several new methods have been introduced in the non-local gluing scheme of ou
In this note, we study symmetry of solutions of the elliptic equation??S2 u+3=e2u on S2, that arises in the consideration of rigidity problem of Hawking mass in
In this paper, we will explore the geometric effects of conformally covariant operators and the induced nonlinear curvature equations in certain nonlocal nature
