Let $X$ be a compact Kähler manifold and $\omega$ be a smooth closed form of bidegree $(1,1)$ which is nonnegative and big. We study the classes ${ℰ}_{\chi }(X,\omega )$ of $\omega$-plurisubharmonic functions of finite weighted Monge-Ampère energy. When the weight $\chi$ has fast growth at infinity, the corresponding functions are close to be bounded. We show that if a positive Radon measure is suitably dominated by the Monge-Ampère capacity, then it belongs to the range of the Monge-Ampère operator on some class ${ℰ}_{\chi }(X,\omega )$. This is done by establishing...

Let $\Omega \subset {ℂ}^n$ be a bounded, simply connected $ℂ$-convex domain. Let $\alpha \in {\mathbb{Z}}_{+}^n$ and let $f$ be a function on $\Omega$ which is separately $C^{2{\alpha }_j-1}$-smooth with respect to $z_j$ (by which we mean jointly $C^{2{\alpha }_j-1}$-smooth with respect to $\mathrm{Re}{z}_j$, $\mathrm{Im}{z}_j$). If $f$ is $\alpha$-analytic on $\Omega \setminus f^{-1}\left(0\right)$, then $f$ is $\alpha$-analytic on $\Omega$. The result is well-known for the case ${\alpha }_i=1$, $1\le i\le n$, even when $f$ a priori is only known to be continuous.

For complex algebraic varieties V, the strong radial Phragmén-Lindelöf condition (SRPL) is defined. It means that a radial analogue of the classical Phragmén-Lindelöf Theorem holds on V. Here we derive a sufficient condition for V to satisfy (SRPL), which is formulated in terms of local hyperbolicity at infinite points of V. The latter condition as well as the extension of local hyperbolicity to varieties of arbitrary codimension are introduced here for the first time. The proof of the main result...

$C^{1,1}$ regularity of the solutions of the complex Monge-Ampère equation in ℂPⁿ with the n-root of the right hand side in $C^{1,1}$ is proved.

We prove a comparison principle for the log canonical threshold of plurisubharmonic functions under an assumption on complex Monge-Ampère measures.

We give sufficient conditions for unicity of plurisubharmonic functions in Cegrell classes.

Soit $G_{\mathbf{C}}$ un groupe de Lie complexe et $G_{\mathbf{R}}$ une forme réelle fermée de $G_{\mathbf{C}}$. Un couple $(G_{\mathbf{C}},G_{\mathbf{R}})$ est dit pseudo-convexe, s’il existe sur $G_{\mathbf{C}}$ une fonction régulière, strictement p.s.h., invariante par l’action de $G_{\mathbf{R}}$ et d’exhaustion sur $G_{\mathbf{C}}/G_{\mathbf{R}}$. On dit que $G_{\mathbf{R}}$ est à spectre imaginaire pur, si pour tout $X$ de Lie$\left(G_{\mathbf{R}}\right)$, les valeurs propres de ad$X$ sont imaginaires pures. Pour $G_{\mathbf{C}}$ à radical simplement connexe, cette dernière propriété équivaut à la pseudo-convexité de $(G_{\mathbf{C}},G_{\mathbf{R}})$. Pour $(G_{\mathbf{C}},G_{\mathbf{R}})$ pseudo-convexe et sous une hypothèse de sous-groupe discret,...

We consider a nondegenerate holomorphic map $f:V\mapsto X$ where $(X,\omega )$ is a compact Hermitian manifold of dimension larger than or equal to $k$ and $V$ is an open connected complex manifold of dimension $k$. In this article we give criteria which permit to construct Ahlfors’ currents in $X$.

We prove an extension theorem for Kähler currents with analytic singularities in a Kähler class on a complex submanifold of a compact Kähler manifold.
