A note on the lower bounds of the first nonzero Steklov eigenvalue on compact manifolds

Yiwei Liu, Yi-Hu Yang

Let $(I^c ◯^{n + 1}, g)$ be an $(n + 1)$ -dimensional smooth compact connected Riemannian manifold with smooth boundary $I^£$ , satisfying that $Ric_{I^} c ◯ \geq 0$ and $I^£$ is strictly co…

Some rigidity results related to the Obata type equation

Yiwei Liu, Yihu Yang

Let $(I^c ◯^{n + 1}, g)$ be an $(n + 1)$ -dimensional smooth complete connected Riemannian manifold with compact boundary $\partial I^c ◯ = I^£$ and $f$ a smooth function on $I^c ◯$ which satisfies…
