This workshop will be devoted to the
complex Monge-Ampere equation and its applications in complex
geometry and analysis.
The main topics of the workshop are:
- The Iitaka conjecture: the approach outlined by H. Tsuji for this famous
problem in complex algebraic geometry makes use of a family of complex
Monge-Ampere equations with degenerate right hand side, and the
crux of the matter is understanding the variation of solutions of such
- The partial $C^0$ estimate: this result states the existence of a uniform
lower bound for the Bergman kernel associated to a power of an ample
Hermitian line bundle, provided that we fix a few natural geometric
invariants, and was recently proved by Donaldson and Sun. As it stands by
now, the proof of this result is using in an essential manner subtle
differential-geometric techniques, namely the Gromov-Hausdorff convergence
theory. On the other hand, it can also be viewed as a quantitative version
of a Fujita-type theorem in algebraic geometry. We intend to analyze
further the analogy between these important achievements in complex
- Symmetrization and complex isoperimetric inequalities: the main part of a
famous result of Kolodziej is a local $L^p$-estimate for the complex
Monge-Ampere equation. The proof is very technical, and uses
pluripotential theory. It would interesting to obtain a purely PDE proof
of this result. The work of Talenti, Tso and Trudinger on real operators
suggests that the right approach should be through a symmetrization result
for the complex Monge-Ampere equation, which would follow from
conjectural complex isoperimetric inequalities.
