Complex Variable Approach for Thermoelastic Boundary Value Problem Using Rational Mapping Techniques

open access: yesMathematics
This article presents a novel approach to looking at steady-state thermoelastic boundary value problems in isotropic elastic plates with curvilinear holes using a complex variable approach and rational conformal mappings.

Pluricomplex Green's functions and Fano manifolds [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2019
We show that if a Fano manifold does not admit Kahler-Einstein metrics then the Kahler potentials along the continuity method subconverge to a function with analytic singularities along a subvariety which solves the homogeneous complex Monge-Ampere ...

Complex Riemannian Spacetime: Removal of Black Hole Singularities and Black Hole Paradoxes

open access: yesAxioms
An approach is presented to resolve key paradoxes in black hole physics through the application of complex Riemannian spacetime. We extend the Schwarzschild metric into the complex domain, employing contour integration techniques to remove singularities ...

One complex variable versus several complex variables: The Hartogs extension phenomenon in context [PDF]

open access: yesOpuscula Mathematica
We explicate the difference between the function theory of one complex variable and the function theory of several complex variables. In particular, we use the inhomogeneous Cauchy-Riemann equations to explain why there is a Hartogs extension phenomenon ...

Complex Riemannian Spacetime and Singularity-Free Black Holes and Cosmology

open access: yesAxioms
An approach is presented to address singularities in general relativity using a complex Riemannian spacetime extension. We demonstrate how this method can be applied to both black hole and cosmological singularities, specifically focusing on the ...

Properties of composite positive continuous functions in $\mathbb{C}^n$

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2015
The properties of positive continuous functions with $Q^n_{\mathbf{b}}$ and $Q$ are investigated. We prove that some composite functions with $Q$ belong to class $Q^n_{\mathbf{b}}.$ A relation between functions with these classes are established.

Removable singularities for hardy spaces [PDF]

open access: yes, 1998
In this paper we study removable singularities for Hardy spaces of analytic funtions on general domains. Two different definitions are given. For compact sets they turn out to be equal and moreover independent of the surrounding domain, as was proved by ...

Cryptographic Puzzles and Complex Systems

open access: yes, 2021
A puzzle lies behind password authentication (PA) and blockchain proof of work (PoW). A cryptographic hash function is commonly used to implement them. The potential problem with secure hash functions is their complexity and rigidity.

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Numerical Resolution of Differential Equations Using the Finite Difference Method in the Real and Complex Domain

open access: yesMathematics
The paper expands the finite difference method to the complex plane, and thus obtains an improvement in the resolution of differential equations with an increase in numerical precision and a generalization in the mathematical modeling of problems.
