New proof of Aubin-Yau theorem for complex non-Kähler manifolds.

problem Transversally Kähler foliations as a generalization of Kähler manifolds.
method Adapting classical Aubin-Yau methods to transversally Kähler case under homological orientability condition.
result New, simpler proof of Vaisman Aubin-Yau theorem.

In the previous papers \cite{L1, L2} the author constructed Mabuchi and Aubin-Yau functionals over any complex surfaces and three-folds, respectively. Using the method in \cite{L2}, we construct those functionals over any complex manifolds of the complex dimension bigger than or equal to 2.

In this note we construct Mabuchi LωM\mathcal{L}^{\rm M}_ω functional and Aubin-Yau functionals IωAY,JωAY\mathcal{I}^{\rm AY}_ω, \mathcal{J}^{\rm AY}_ω on any compact complex surfaces, and establish a number of properties. Our construction coincides with the original one in the Kähler case.

In this paper we construct Mabuchi LωM\mathcal{L}^{\rm M}_ω functional and Aubin-Yau functionals IωAY,JωAY\mathcal{I}^{\rm AY}_ω, \mathcal{J}^{\rm AY}_ω on any compact complex three-folds. The method presented here will be used in the forthcoming paper \cite{L1} on the construction of those functionals on any compact complex m…

Simplified proof and new C0C^0 estimate for Kähler-Einstein metrics.

problem Existence of Kähler-Einstein metrics on Calabi-Yau manifolds.
method Alternative C0C^0 a priori estimate for the Monge-Ampère equation.
result Established a new uniform bound for the solution of the Monge-Ampère equation.

This is the content of the lectures given by the author at the winter school KAWA3 held at the University of Barcelona in 2012 from January 30 to February 3. The main goal was to give an account of viscosity techniques and to apply them to degenerate Complex Monge-Ampère equations following recent works of P. Eyssidieu…

In this note, we propose a new approach to solving the Calabi problem on manifolds with edge-cone singularities of prescribed angles along complex hypersurfaces. It is shown how the classical approach of Aubin-Yau in derving {\it a priori} estimates for the complex hessian can be made to work via adopting a \emph{good …

We study the free energy of the Laughlin state on curved backgrounds, starting from the free field representation. A simple argument, based on the computation of the gravitational effective action from the transformation properties of Green functions under the change of the metric, allows to compute the first three ter…

We associate certain probability measures on R\R to geodesics in the space $\H_L$ of positively curved metrics on a line bundle LL, and to geodesics in the finite dimensional symmetric space of hermitian norms on H0(X,kL)H^0(X, kL). We prove that the measures associated to the finite dimensional spaces converge weakly to t…

method Extending the surface-graph approach to noncommutative settings, the paper analyzes the topological properties of graphs embedded on surfaces of different genera.
result Theorems associated with graphs on the sphere hold over any division ring, while those on surfaces of positive genus typically hold only if the ground ring is a field.
