Closed 3‐forms in five dimensions and embedding problems

open access: yesJournal of the London Mathematical Society, Volume 109, Issue 4, April 2024.
Abstract We consider the question if a five‐dimensional manifold can be embedded into a Calabi–Yau manifold of complex dimension 3 such that the real part of the holomorphic volume form induces a given closed 3‐form on the 5‐manifold. We define an open set of 3‐forms in dimension five which we call strongly pseudoconvex, and show that for closed ...

Optimizing Artificial Neural Network Learning Using Improved Reinforcement Learning in Artificial Bee Colony Algorithm

open access: yesApplied Computational Intelligence and Soft Computing, Volume 2024, Issue 1, 2024.
Artificial neural networks (ANNs) are widely used machine learning techniques with applications in various fields. Heuristic search optimization methods are typically used to minimize the loss function in ANNs. However, these methods can lead the network to become stuck in local optima, limiting performance.

Boundary Schwarz Lemma for Holomorphic Self-mappings of Strongly Pseudoconvex Domains [PDF]

open access: yesComplex Analysis and Operator Theory, 2016
In this paper, we generalize a recent work of Liu et al. from the open unit ball $\mathbb B^n$ to more general bounded strongly pseudoconvex domains with $C^2$ boundary. It turns out that part of the main result in this paper is in some certain sense just a part of results in a work of Bracci and Zaitsev. However, the proofs are significantly different:

The Automorphism Group of a Domain with an Exponentially Flat Boundary Point [PDF]

open access: yes, 2010
We study the automorphisms group action on a bounded domain in $\CC^n$ having a boundary point that is exponentially flat. Such a domain typically has a compact automorphism group.

Manifolds of holomorphic mappings from strongly pseudoconvex domains [PDF]

open access: yesAsian Journal of Mathematics, 2007
Let D be a bounded strongly pseudoconvex domain in a Stein manifold S and let Y be a complex manifold. We prove that the graph of any continuous map from the closure of D to Y which is holomorphic in D admits a basis of open Stein neighborhoods in S x Y.

Admissible limits of bloch functions on bounded strongly pseudoconvex domains [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1996
Let be a bounded strongly pseudoconvex domain with C2 boundary . In this paper we prove that for a Bloch function in the existance of radial limits at almost all implies the existence of admissible limits almost everywhere on .

Some Characterizations of Bloch Functions on Strongly Pseudoconvex Domains

open access: yesTokyo Journal of Mathematics, 1994
This paper contains 3 characterisations of Bloch functions on smoothly bounded, strongly pseudoconvex domains in terms of invariant geometry, Bergman-Carleson measures and certain invariant random processes, respectively. This involves extending and modifying earlier work by \textit{J. Choa}, \textit{H. Kim} and \textit{Y. Park} [Bull. Korean Math. Soc.

Some characterizations of Bloch functions on strongly pseudoconvex domains [PDF]

open access: yesColloquium Mathematicum, 1992
The main result of the paper is the following theorem. Let \(D\) be a strongly pseudoconvex domain in \(\mathbb{C}^ n\) with defining function \(\rho\). Let \(F_ K^ D\), \(d_ K\) denote the Kobayashi-Royden metric and the Kobayashi distance for \(D\), respectively. Put \(B_ K(q,r):=\{z\in D\): \(d_ K(q,z)
