The gradient lemma

Urban Cegrell (2007)

Annales Polonici Mathematici

We show that if a decreasing sequence of subharmonic functions converges to a function in W l o c 1 , 2 then the convergence is in W l o c 1 , 2 .

The growth of regular functions on algebraic sets

A. Strzeboński (1991)

Annales Polonici Mathematici

We are concerned with the set of all growth exponents of regular functions on an algebraic subset V of n . We show that its elements form an increasing sequence of rational numbers and we study the dependence of its structure on the geometric properties of V.

The holomorphic automorphism groups of twisted Fock-Bargmann-Hartogs domains

Hyeseon Kim, Atsushi Yamamori (2018)

Czechoslovak Mathematical Journal

We consider a certain class of unbounded nonhyperbolic Reinhardt domains which is called the twisted Fock-Bargmann-Hartogs domains. By showing Cartan's linearity theorem for our unbounded nonhyperbolic domains, we give a complete description of the automorphism groups of twisted Fock-Bargmann-Hartogs domains.

The holomorphic extension of C k CR functions on tube submanifolds

Al Boggess (1998)

Annales Polonici Mathematici

We show that a CR function of class C k , 0 ≤ k < ∞, on a tube submanifold of n holomorphically extends to the convex hull of the submanifold. The extension and all its derivatives through order k are shown to have nontangential pointwise boundary values on the original tube submanifold. The C k -norm of the extension is shown to be no bigger than the C k -norm of the original CR function.

The homogeneous transfinite diameter of a compact subset of N

Mieczysław Jędrzejowski (1991)

Annales Polonici Mathematici

Let K be a compact subset of N . A sequence of nonnegative numbers defined by means of extremal points of K with respect to homogeneous polynomials is proved to be convergent. Its limit is called the homogeneous transfinite diameter of K. A few properties of this diameter are given and its value for some compact subsets of N is computed.
