The Weyl functional on 4-manifolds of positive Yamabe invariant

Chanyoung Sung

It is shown that on every closed oriented Riemannian 4-manifold $(M, g)$ with positive scalar curvature, $\int_{M} ∣ W_{g}^{+} ∣^{2} d μ_{g} \geq 2 π^{2} (2 χ (M) + 3 τ (M)) - \frac{8 π ^{2}}{∣ π _{1} ( M ) ∣},$ where…

Fiberwise symmetrizations for variational problems on fibred manifolds

Chanyoung Sung

We establish a framework for fiberwise symmetrization to find a lower bound of a Dirichlet-type energy functional in a variational problem on a fibred Riemannian manifold, and use…
