Abstract We consider the Fock–Bargmann–Hartogs domain D n,m which is defined by inequality where (z, ζ) ∈ ℂ n × m and μ > 0. give an explicit formula for Bergman kernel of in terms polylogarithm functions. Moreover, using interlacing property, we describe how existence zeros depends on integers n.

It was shown by Kaup that every origin-preserving automorphism of quasi-circular domains is a polynomial mapping. In this paper, we study how the weight and degree such automorphisms are related. By using Bergman mapping, prove normal in C2 linear.

In the study of holomorphic automorphism groups, many researches have been carried out inside category bounded or hyperbolic domains. On contrary to these cases, for unbounded non-hyperbolic only a few results are known about structure groups. Main result present paper gives class Reinhardt domains with non-compact Cartan's linearity theorem and explicit Bergman kernels. Moreover, reformulation finite volume is also given.

The optimal treatment for profound hyponatraemia remains uncertain. Recent clinical studies have demonstrated that a standardized bolus of hypertonic saline is effective, but relying solely on this approach may not fully address the individual variability among patients. We evaluated effectiveness rapid (RB) administration followed by predictive correction (PC) using an infusate and fluid loss formula identical to Barsoum-Levine based Edelman equation (RB-PC) managing hyponatraemia. In...

A theorem due to Cartan asserts that every origin-preserving automorphism of bounded circular domains with respect the origin is linear. In present paper, by employing theory Bergman's representative domain, we prove under certain circumstances Cartan's assertion remains true for quasi-circular in $\mathbb C^n$. Our main result applied obtain some simple criterions case $n=3$ and Braun-Kaup-Upmeier's our class domains.
