In this article we continue the investigations on invariant metrics on a certain class of weakly pseudoconvex domains which we began in [H 1]. While in that paper the differential metrics of Caratheodory and Kobayashi were estimated precisely, the present paper contains a sharp estimate of the singularity of the Bergman kernel and metric on domains belonging to that class.

AbstractIt is well known in Kähler geometry that the infinite-dimensional symmetric space $\mathcal{H}$ of smooth Kähler metrics in a fixed Kähler class on a polarized Kähler manifold is well approximated by finite-dimensional submanifolds $\mathcal{B}_k\subset\mathcal{H}$ of Bergman metrics of height k. Then it is natural to ask whether geodesics in $\mathcal{H}$ can be approximated by Bergman geodesics in $\mathcal{B}_k$. For any polarized Kähler manifold, the approximation is in the C0 topology. For some special varieties, one expects better convergence: Song and Zelditch proved the C2 convergence for the torus-invariant metrics over toric varieties. In this article, we show that some C∞ approximation exists as well as a complete asymptotic expansion for principally polarized abelian varieties.

Let X be a domain in a closed polarized complex manifold (Y,L), where L is a (semi-) positive line bundle over Y. Any given Hermitian metric on L induces by restriction to X a Hilbert space structure on the space of global holomorphic sections on Y with values in the k-th tensor power of L (also using a volume form ωn on X. In this paper the leading large k asymptotics for the corresponding Bergman kernels and metrics are obtained in the case when X is a pseudo-concave domain with smooth boundary (under a certain compatibility assumption). The asymptotics are expressed in terms of the curvature of L and the boundary of X. The convergence of the Bergman metrics is obtained in a more general setting where (X,ωn) is replaced by any measure satisfying a Bernstein–Markov property. As an application the (generalized) equilibrium measure of the polarized pseudo-concave domain X is computed explicitly. Applications to the zero and mass distribution of random holomorphic sections and the eigenvalue distribution of Toeplitz operators will be described elsewhere.

Let [Formula: see text] be a globally defined real Kähler potential on a domain [Formula: see text], and [Formula: see text] be a Kähler metric on the Hartogs domain [Formula: see text] associated with the Kähler potential [Formula: see text]. First, we obtain explicit formulas of the coefficients [Formula: see text] of the Bergman function expansion for the Hartogs domain [Formula: see text] in a momentum profile [Formula: see text]. Second, using explicit expressions of [Formula: see text], we obtain necessary and sufficient conditions for the coefficients [Formula: see text] to be constants. Finally, we obtain all the invariant complete Kähler metrics on Cartan–Hartogs domains such that their the coefficients [Formula: see text] of the Bergman function expansions are constants.

A Kähler metric [Formula: see text] with integral Kähler form is said to be partially regular if the partial Bergman kernel associated to [Formula: see text] is a positive constant for all integer [Formula: see text] sufficiently large. The aim of this paper is to prove that for all [Formula: see text] there exists an [Formula: see text]-dimensional complex manifold equipped with strictly partially regular and cscK metric [Formula: see text]. Further, for [Formula: see text], the (constant) scalar curvature of [Formula: see text] can be chosen to be zero, positive or negative.

This thesis deals with two different subjects: balanced metrics on complex vector bundles and the diastatic exponential of a symmetric space. Correspondingly we have two main results. In the first one we prove that if a holomorphic vector bundle E over a compact Kähler manifold (M,ω) admits a ω-balanced metric then this metric is unique. In the second one, after defining the diastatic exponential of a real analytic Kähler manifold, we prove that for every point p of an Hermitian symmetric space of noncompact type there exists a globally defined diastatic exponential centered in p which is a diffeomorphism and it is uniquely determined by its restriction to polydisks.

La tesi si articola in quattro capitoli. Nel primo capitolo vengono esposti i concetti di base su cui è basata la teoria principale. Inizieremo ricordando le definizioni e i teoremi più rilevanti sugli spazi di Hilbert, sui sistemi ortonormali e sulle funzioni olomorfe per poi arrivare al prodotto Wedge, agli operatori bilineari e al prodotto tensoriale. Il secondo capitolo è destinato ai nuclei riproducenti. Vedremo dapprima la definizione e il Teorema di Aronszajn-Bergman che determina una condizione necessaria e sufficiente sugli spazi affinchè abbiano nucleo riproducente. Studieremo poi le proprietà degli spazi dotati di tale nucleo. Nel terzo capitolo viene illustrato il nucleo di Bergman. Partiremo cercando una stima dell'integrale sui polidischi di C^n di funzioni a quadrato integrabile per poi analizzare il sottospazio generato dalle funzioni olomorfe a quadrato integrabile. Vedremo poi che i risultati ottenuti integrando con la misura di Lebesgue su C^n valgono anche integrando con una misura con peso. Nel quarto ed ultimo capitolo arriveremo al punto saliente della trattazione. Determineremo il proiettore ortogonale dallo spazio delle funzioni a quadrato integrabile allo spazio delle funioni olomorfe a quadrato integrabile e, sotto certe condizioni, prenderemo una determinazione di logaritmo di queste ultime. Grazie alla determinazione di logaritmo costruiremo una forma differenziale hermitiana invariante rispetto agli automorfismi olomorfi dei domini di C^n . Infine, daremo delle ipotesi sotto le quali la forma hermitiana è definita positiva: arriveremo così a definire la metrica che ne deriva. Essa sarà la metrica di Bergman.

Let ½ Cm be a bounded domain and K :£!C be a sesqui-analytic function. We show that if ®,¯ È 0 be such that the functions K® and K¯, defined on £, are non-negative definite kernels, then theMm(C) valued function K(®,¯)(z,w) :Æ K®Å¯(z,w) ³ ¡ @i¯@ j logK ¢ (z,w) ´m i , jÆ1 , z,w 2, is also a non-negative definite kernel on £. Then a realization of the Hilbert space (H,K(®,¯)) determined by the kernel K(®,¯) in terms of the tensor product (H,K®)(H,K¯) is obtained. For two reproducing kernel Hilbert modules (H,K1) and (H,K2), let An, n ¸ 0, be the submodule of the Hilbert module (H,K1)(H,K2) consisting of functions vanishing to order n on the diagonal set ¢ :Æ {(z, z) : z 2}. Setting S0 ÆA? 0 , Sn ÆAn¡1ªAn, n ¸ 1, leads to a natural decomposition of (H,K1)(H,K2) into infinite direct sum L1 nÆ0Sn. A theorem of Aronszajn shows that the module S0 is isomorphic to the push-forward of the module (H,K1K2) under the map ¶ : !£, where ¶(z) Æ (z, z), z 2 . We prove that if K1 Æ K® and K2 Æ K¯, then the module S1 is isomorphic to the push-forward of the module (H,K(®,¯)) under the map ¶. Let Möb denote the group of all biholomorphic automorphisms of the unit disc D. An operator T in B(H) is said to be weakly homogeneous if ¾(T ) µ ¯D and '(T ) is similar to T for each ' inMöb. For a sharp non-negative definite kernel K : D£D!Mk(C), we show that the multiplication operator Mz on (H,K) is weakly homogeneous if and only if for each ' in Möb, there exists a g' 2Hol(D,GLk(C)) such that the weighted composition operator Mg'C'¡1 is bounded and invertible on (H,K). We also obtain various examples and nonexamples of weakly homogeneous operators in the class FB2(D). Finally, it is shown that there exists a Möbius bounded weakly homogeneous operator which is not similar to any homogeneous operator. We also show that if K1 and K2 are two positive definite kernels on D£D such that the multiplication operators Mz on the corresponding reproducing kernel Hilbert spaces are subnormal, then the multiplication operator Mz on the Hilbert space determined by the sum K1ÅK2 need not be subnormal. This settles a recent conjecture of Gregory T. Adams, Nathan S. Feldman and Paul J.McGuire in the negative.
