Liouville-type theorems and applications to geometry on complete Riemannian manifolds

Chanyoung Sung

On a complete Riemannian manifold M with Ricci curvature satisfying $Ric (\nabla r, \nabla r) \geq - A r^{2} (lo g r)^{2} (lo g (lo g r))^{2} ... (lo g^{k} r)^{2}$ for $r ≫ 1$ , where A>0…

Surgery and equivariant Yamabe invariant

Chanyoung Sung

We consider the equivariant Yamabe problem, i.e. the Yamabe problem on the space of G-invariant metrics for a compact Lie group G. The G-Yamabe invariant is analogously defined as…
