The dirichlet boundary conditions and related natural boundary conditions in strengthened sobolev spaces for discretized parabolic problems

open access: yesDiscrete Dynamics in Nature and Society, 2000
Correctness of initial boundary value problems and their discretizations are analyzed under unusual second-order boundary conditions, which can be considered as natural boundary conditions in strengthened Sobolev spaces and as improvements (in some cases)

Weak Solutions for a Class of Nonlocal Singular Problems Over the Nehari Manifold

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a nonlocal model of dilatant non‐Newtonian fluid with a Dirichlet boundary condition. By using the Nehari manifold and fibering map methods, we obtain the existence of at least two weak solutions, with sign information.

Boundary element method for Laplace equation in a ring domain

open access: yesPartial Differential Equations in Applied Mathematics
In this paper, we present a rapid procedure for approximating the solution to the Laplace equation in a ring domain. We develop a new formulation of boundary integral operators and implement an efficient solution approach using the Galerkin boundary ...

Low frequency acoustic and electromagnetic scattering [PDF]

open access: yes
This paper deals with two classes of problems arising from acoustics and electromagnetics scattering in the low frequency stations. The first class of problem is solving Helmholtz equation with Dirichlet boundary conditions on an arbitrary two ...

Linear Toroidal‐Inertial Waves on A Differentially Rotating Sphere with Application to Helioseismology: Modeling, Forward and Inverse Problems

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on the sphere, the stream function of the flow satisfies a fourth‐order scalar equation.

Solving the Dirichlet problem constructively

open access: yesJournal of Logic and Analysis, 2013
The paper considers the existence of constructive solutions for Dirichlet's boundary value problem for open, bounded integrable sets \(\Omega\subseteq\mathbb{R}^n\) and uniformly continuous boundary conditions \(f : \partial\Omega \to \mathbb{R}\). It is shown that: in presence of Markov's Principle, the existence of a weak solution for the Dirichlet ...

From Inclusion to Sustainability: A Systematic Review of Research Trends in Sustainable Inclusive Education (2015–2025)

open access: yesSustainable Development, EarlyView.
ABSTRACT This systematic review reconceptualizes inclusive education (IE) as a cross‐cutting strategy for sustainable development. We analyze 2729 articles published between 2015 and 2025, identifying 357 that explicitly address sustainability. Using PRISMA 2020, bibliometric mapping, and binomial generalized linear models, we examine temporal ...

Fragmentation Across Scales, Geography, and Climate Challenges in European Urban Climate Change Adaptation and Mitigation Research: A Bibliometric and Systematic Review

open access: yesSustainable Development, EarlyView.
ABSTRACT European urban climate change research lacks integration across scales, geography, and climate challenges, despite Europe's coordinated policy frameworks. Through a hybrid bibliometric and systematic review of 1528 studies (2010–2025) using Cortext Manager and PRISMA 2020 guidelines, this study maps the conceptual patterns, knowledge gaps, and

Integrating multimodal data and machine learning for entrepreneurship research

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Extant research in neuroscience suggests that human perception is multimodal in nature—we model the world integrating diverse data sources such as sound, images, taste, and smell. Working in a dynamic environment, entrepreneurs are expected to draw on multimodal inputs in their decision making.
