Generic subgroups of Aut 𝔹 n

Chiara de Fabritiis (2002)

Annali della Scuola Normale Superiore di Pisa - Classe di Scienze

We prove that for a parabolic subgroup Γ of Aut 𝔹 n the fixed points sets of all elements in Γ { id 𝔹 n } are the same. This result, together with a deep study of the structure of subgroups of Aut 𝔹 n acting freely and properly discontinuously on 𝔹 n , entails a generalization of the so called weak Hurwitz’s theorem: namely that, given a complex manifold X covered by 𝔹 n and such that the group of deck transformations of the covering is “sufficiently generic”, then id X is isolated in Hol ( X , X ) .

Holomorphic functions of fast growth on submanifolds of the domain

Piotr Jakóbczak (1998)

Annales Polonici Mathematici

We construct a function f holomorphic in a balanced domain D in N such that for every positive-dimensional subspace Π of N , and for every p with 1 ≤ p < ∞, f | Π D is not L p -integrable on Π ∩ D.

Integral representations for some weighted classes of functions holomorphic in matrix domains

M. M. Djrbashian, A. H. Karapetyan (1991)

Annales Polonici Mathematici

In 1945 the first author introduced the classes H p ( α ) , 1 ≤ p<∞, α > -1, of holomorphic functions in the unit disk with finite integral (1) ∬ |f(ζ)|p (1-|ζ|²)α dξ dη < ∞ (ζ=ξ+iη) and established the following integral formula for f H p ( α ) : (2) f(z) = (α+1)/π ∬ f(ζ) ((1-|ζ|²)α)/((1-zζ̅)2+α) dξdη, z∈ . We have established that the analogues of the integral representation (2) hold for holomorphic functions in Ω from the classes L p ( Ω ; [ K ( w ) ] α d m ( w ) ) , where: 1) Ω = w = ( w , . . . , w n ) n : I m w > k = 2 n | w k | ² , K ( w ) = I m w - k = 2 n | w k | ² ; 2) Ω is the matrix domain consisting of those complex m...
