Fourth-order geometric flows and integral pinching of the curvature
We study fourth-order geometric flows on compact Riemannian manifolds, which naturally appear as gradient flows of quadratic curvature functionals. When the Yamabe... -
Sign-Preserving Property for Some Fourth-Order Elliptic Operators in One Dime...
For a class of one-dimensional linear elliptic fourth-order equations with homogeneous Dirichlet boundary conditions it is shown that a non-positive and non-vanishing...
