On groups of formal diffeomorphisms of several complex variables

open access: yesAnais da Academia Brasileira de Ciências, 2012
In this note we announce some results in the study of groups of formal or germs of analytic diffeomorphisms in several complex variables. Such groups are related to the study of the transverse structure and dynamics of Holomorphic foliations, via the ...

On Functions of Several Complex Variables [PDF]

open access: yesTransactions of the American Mathematical Society, 1916
By means of certain very simple examples it is possible to decide a number of questions relating to analytic functions of several complex variables, which have hitherto, so far as the author is aware, remained open. It is unsatisfactory, in stating an important theorem, not to know whether a given hypothesis is needed merely for convenience of proof ...

Hardy’s inequality for functions of several complex variables [PDF]

open access: yes, 2017
We obtain a generalization of Hardy’s inequality for functions in the Hardy space H1 (Bd), where Bd is the unit ball {z = (z1, …, zd) ∈ In particular, we construct a function φ on the set of d –dimensional multi-indices {n = (n1, …, nd) | ni ∈ {0 ...

On Some Branched Continued Fraction Expansions for Horn’s Hypergeometric Function H4(a,b;c,d;z1,z2) Ratios

open access: yesAxioms, 2023
The paper deals with the problem of representation of Horn’s hypergeometric functions by branched continued fractions. The formal branched continued fraction expansions for three different Horn’s hypergeometric function H4 ratios are constructed.

Projections in several complex variables [PDF]

open access: yesMémoires de la Société mathématique de France, 2010
This work consists two parts. In the first part, we completely study the heat equation method of Menikoff-Sjostrand and apply it to the Kohn Laplacian defined on a compact orientable connected CR manifold. We then get the full asymptotic expansion of the Szego projection for (0,q) forms when the Levi formis nondegenerate.

The residue calculus in several complex variables [PDF]

open access: yesTransactions of the American Mathematical Society, 1974
Let W be a complex manifold and V an analytic variety. Then homology classes in W − V W - V which bound in V, called the geometric residues, are studied. In fact, a long exact sequence analogous to the Thom-Gysin sequence for nonsingular V is formed by a geometric construction. A geometric interpretation of the

Degeneracy and finiteness theorems for meromorphic mappings in several complex variables [PDF]

open access: yes, 2017
In this article, we prove that there are at most two meromorphic mappings of $\mathbb C^m$ into $\mathbb P^n(\mathbb C)\ (n\geqslant 2)$ sharing $2n+2$ hyperplanes in general position regardless of multiplicity, where all zeros with multiplicities more ...

Kernel convergence and biholomorphic mappings in several complex variables

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
We deal with kernel convergence of domains in ℂn which are biholomorphically equivalent to the unit ball B. We also prove that there is an equivalence between the convergence on compact sets of biholomorphic mappings on B, which satisfy a growth theorem,
