Singular hyperbolic metrics and negative subharmonic functions
Yu Feng, Yiqian Shi, Jijian Song +1
We propose a conjecture that the monodromy group of a singular hyperbolic metric on a non-hyperbolic Riemann surface is {\it Zariski dense} in . By using m…
Characterizing isolated singularities of conformal hyperbolic metrics
Yu Feng, Yiqian Shi, Bin Xu
We find the explicit local models of isolated singularities of conformal hyperbolic metrics by Complex Analysis, which is interesting in its own and could potentially be extended t…
Gradient estimate of an eigenfunction on a compact Riemannian manifold without boundary
Yiqian Shi, Bin Xu
Let be an eigenfunction with respect to the Laplace-Beltrami operator on a compact Riemannian manifold without boundary: . We show the following…
The Riemannian manifolds with boundary and large symmetry
Zhi Chen, Yiqian Shi, Bin Xu
Sixty years ago, S. B. Myers and N. E. Steenrod ({\it Ann. of Math.} {\bf 40} (1939), 400-416) showed that the isometry group of a Riemannian manifold without boundary has a struct…
