A counterexample to smooth leafwise Hodge decomposition for general foliations and to a type of dynamical trace formulas
Christopher Deninger, Wilhelm Singhof (2001)
Annales de l’institut Fourier
We construct a two dimensional foliation with dense leaves on the Heisenberg nilmanifold for which smooth leafwise Hodge decomposition does not hold. It is also shown that a certain type of dynamical trace formulas relating periodic orbits with traces on leafwise cohomologies does not hold for arbitrary flows.
A fully nonlinear version of the Yamabe problem on manifolds with boundary
Aobing Li, Yan Yan Li (2006)
Journal of the European Mathematical Society
We propose to study a fully nonlinear version of the Yamabe problem on manifolds with boundary. The boundary condition for the conformal metric is the mean curvature. We establish some Liouville type theorems and Harnack type inequalities.

Conformally bending three-manifolds with boundary
Matthew Gursky, Jeffrey Streets, Micah Warren (2010)
Annales de l’institut Fourier
Given a three-dimensional manifold with boundary, the Cartan-Hadamard theorem implies that there are obstructions to filling the interior of the manifold with a complete metric of negative curvature. In this paper, we show that any three-dimensional manifold with boundary can be filled conformally with a complete metric satisfying a pinching condition: given any small constant, the ratio of the largest sectional curvature to (the absolute value of) the scalar curvature is less than this constant....
