The K\"ahler-Ricci flow, Ricci-flat metrics and collapsing limits
, 2017 We investigate the Kahler-Ricci flow on holomorphic fiber spaces whose generic fiber is a Calabi-Yau manifold. We establish uniform metric convergence to a metric on the base, away from the singular fibers, and show that the rescaled metrics on the ...

On complete Ricci-flat metrics on open Kähler manifolds [PDF]
Matemática Contemporânea, 2006 This paper has two purposes. First it partially extends the result in the author's previous work concerning the asymptotic expansion of the Tian-Yau metrics, by considering a slightly larger class of quasi-projective manifolds. This text is also intended to provide a quick introductory reference to the study of Ricci-flat metrics on open manifolds.

Conformal invariance of (0, 2) sigma models on Calabi-Yau manifolds
Journal of High Energy Physics, 2018 Long ago, Nemeschansky and Sen demonstrated that the Ricci-flat metric on a Calabi-Yau manifold could be corrected, order by order in perturbation theory, to produce a conformally invariant (2, 2) nonlinear sigma model.

On the geometry of generalized nonholonomic Kenmotsu manifolds
Дифференциальная геометрия многообразий фигур, 2022 The concept of a generalized nonholonomic Kenmotsu manifold is introduced. In contrast to the previously defined nonholonomic Kenmotsu manifold, the manifold studied in the article is an almost normal almost contact metric manifold of odd rank.

PLANTS, PEOPLE, PLANET, EarlyView.Plant breeding for agroecological transition (AET) holds the potential to transform agriculture by fostering crop diversification and empowering farmers through collaborative, inter‐ and transdisciplinary research. By adopting a systemic, co‐learning approach, we can deepen our understanding of the complex interactions between plant diversity ...

On M-theory fourfold vacua with higher curvature terms
Physics Letters B, 2015 We study solutions to the eleven-dimensional supergravity action, including terms quartic and cubic in the Riemann curvature, that admit an eight-dimensional compact space.

Journal of High Energy Physics, 2020 We study two-dimensional weighted N $$ \mathcal{N} $$ = (2) supersymmetric ℂℙ models with the goal of exploring their infrared (IR) limit. 𝕎ℂℙ(N, N ˜ $$ \tilde{N} $$ ) are simplified versions of world-sheet theories on non-Abelian strings in four ...

The quantum non-linear σ-model RG flow and integrability in wormhole geometries
Nuclear Physics B, 2023 The target space of the non-linear σ-model is a Riemannian manifold. Although it can be any Riemannian metric, there are certain physically interesting geometries which are worth to study.

Fortschritte der Physik, EarlyView.Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.
