POSITIVITY OF RICCI CURVATURE UNDER THE KÄHLER–RICCI FLOW [PDF]

Communications in Contemporary Mathematics, 2006
In each complex dimension n ≥ 2, we construct complete Kähler manifolds of bounded curvature and non-negative Ricci curvature whose Kähler–Ricci evolutions immediately acquire Ricci curvature of mixed sign.

Policy Evaluation for Climate Mitigations in the European Agricultural Sector—A Comparison of Policy Options at Micro and Macro Level

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The purpose of this paper is to discuss the micro‐ and macro‐outcomes for the standard neoclassical carbon tax (whose burden falls on the producers) versus the implication of a budget neutral, performance‐based EU Common Agricultural Policy (CAP) focusing on non‐CO2 emission (N2O and CH4, measured in CO2eq) reduction, especially in the ...

Optimising the Diagnosis of Sesame Seed Allergy With the Basophil Activation Test

Allergy, EarlyView.
The basophil activation test (using the activation marker CD203c) was the only test able to both exclude and confirm sesame seed allergy with precision. A negative skin prick test to sesame extract or tahini and undetectable IgE to Ses i 1 could not rule out sesame seed allergy.

Geometric and Structural Properties of Indefinite Kenmotsu Manifolds Admitting Eta-Ricci–Bourguignon Solitons

Mathematics
This paper undertakes a detailed study of η-Ricci–Bourguignon solitons on ϵ-Kenmotsu manifolds, with particular focus on three special types of Ricci tensors: Codazzi-type, cyclic parallel and cyclic η-recurrent tensors that support such solitonic ...

Singularities of three-dimensional Ricci flows

, 2016
The Ricci flow is an evolution of a Riemannian metric driven by a parabolic PDEs and was introduced by Hamilton in 1982. It has been the fundamental tool for some important achievements in geometry in the early 2000s, such as Perelman’s proof of the ...

A Spotlight on Yolk‐sac Tumors: Molecular Pathology, Current Diagnostics, and Novel Therapeutics

Andrology, EarlyView.
ABSTRACT Background Yolk‐sac tumors are an aggressive subtype of testicular cancer that significantly contribute to disease progression and therapy resistance, especially in adults. While testicular cancer generally has high cure rates with cisplatin‐based treatment, adult yolk‐sac tumors often appear as components of mixed tumors with poor response to

A note on Kähler–Ricci flow

Mathematische Zeitschrift, 2011
Let $g(t)$ with $t\in [0,T)$ be a complete solution to the Kaehler-Ricci flow: $\frac{d}{dt}g_{i\bar j}=-R_{i\bar j}$ where $T$ may be $\infty$. In this article, we show that the curvatures of $g(t)$ is uniformly bounded if the solution $g(t)$ is uniformly equivalet. This result is stronger than the main result in Šešum \cite{sesum} within the category

Impressions that matter: How Italian SOEs construct a digital image through persuasive language strategies

Financial Accountability &Management, EarlyView.
ABSTRACT Rooted in the theoretical perspective of impression management, and drawing on the critical discourse analysis (CDA) approach, this study analyzes whether and how the Italian state‐owned enterprises (SOEs) in the energy sector over the period 2020–2023 use persuasive language strategies in their annual reports to portray the image of a ...
