Convexity in quasi-metric spaces [PDF]

, 2012
Includes abstract.Includes bibliographical references.The principal aim of this thesis is to investigate the existence of an injective hull in the categories of T-quasi-metric spaces and of T-ultra-quasi-metric spaces with nonexpansive ...

Kantowski–Sachs Model with a Running Cosmological Constant and Radiation

Universe
The simplest anisotropic model of the early universe is the one with two conformal factors, which can be identified as the Kantowski–Sachs metric, or the reduced version of the Bianchi-I metric.

Compositional Time–Temperature–Transformation and Post‐Processing Window Mapping of Epoxy Nanocomposites via Machine Learning

Journal of Applied Polymer Science, EarlyView.
Discrete DSC and rheological data are transformed into continuous compositional Time–temperature–transformation (TTT) diagrams through physics‐informed Gaussian Process Regression. The proposed framework quantitatively predicts post‐gel processing windows across temperature and nanofiller composition, providing a practical route for accelerated design ...

Spontaneous CPT breaking and fermion propagation in the Schwarzschild geometry

Physics Letters B, 2019
The Schwarzschild solution is used as a background metric to analyze the effects of a vector field undergoing spontaneous symmetry breaking in a Standard Model Extension Bumblebee Model. The corresponding back-reaction of the background field expectation

UNIQUE FIXED POINT THEOREMS FOR CONTRACTIVE MAPS TYPE IN T 0 -QUASI-METRIC SPACES [PDF]

, 2014
In [2], Agyingi proved that every generalized contractive mapping defined in a q-spherically complete T 0 -ultra-quasi-metric space has a unique fixed point.

Sustainable Development Goals' Discourse in the Accounting and Business Literature: A Rhetorical Lens

Business Strategy and the Environment, EarlyView.
ABSTRACT The role of academia in shaping the Sustainable Development Goals (SDGs) remains insufficiently understood. This study examines how SDG discourse is constructed within accounting and business research by integrating bibliometric analysis with a systematic review of 731 peer‐reviewed articles published between 2020 and 2024.

Nuove fonti per le origini dei Bianchi

, 2001
L'autore amplia ulteriormente lo spettro delle fonti relative al tema dei Bianchi, rispetto a quanto compiuto in precedenza, ribadendone dei prodromi precedenti il 1399 e indicando possibili contatti con tendenze esterne al territorio peninsulare ...

Asymptotically Euclidean Bianchi IX metrics in quantum gravity

Physics Letters B, 1978
We present a class of exact self-dual metrics of Bianchi IX type with all directions unequal. Although asymptotically Euclidean they may not be considered as gravitational instantons since they contain singularities. This accords with the Positive Action Conjecture.

Government Subsidies for Industrial Symbiosis: Is It Always Worth It? Assessing Effectiveness and Efficiency Through Agent‐Based Modeling

Business Strategy and the Environment, EarlyView.
ABSTRACT Policy intervention can be a driver for industrial symbiosis (IS). However, given the wide variety of policy instruments available, policymakers should be guided in the policy design process to ensure that their intervention is effective and efficient. In this paper, we propose an agent‐based (AB) model intended to assess the effectiveness and

Hyperconvexity and endpoints in T₀-quasi-metric spaces [PDF]

, 2013
Over the last decades much progress has been made in the investigation of hyperconvexity in metric spaces. Recently Kemajou and others have published an article concerning hyperconvexity in T₀-quasi-metric spaces.
