An Introduction to the Kähler-Ricci Flow [PDF]
, 2013 This volume collects lecture notes from courses offered at several conferences and workshops, and provides the first exposition in book form of the basic theory of the Kähler-Ricci flow and its current state-of-the-art. While several excellent books on Kähler-Einstein geometry are available, there have been no such works on the Kähler-Ricci flow.

Ricci flows with unbounded curvature [PDF]
Mathematische Zeitschrift, 2012 Until recently, Ricci flow was viewed almost exclusively as a way of deforming Riemannian metrics of bounded curvature. Unfortunately, the bounded curvature hypothesis is unnatural for many applications, but is hard to drop because so many new phenomena can occur in the general case.

On the stability of harmonic maps under the homogeneous Ricci flow
Complex Manifolds, 2018 In this work we study properties of stability and non-stability of harmonic maps under the homogeneous Ricci flow.We provide examples where the stability (non-stability) is preserved under the Ricci flow and an example where the Ricci flow does not ...

The spinorial energy for asymptotically Euclidean Ricci flow
Advanced Nonlinear Studies, 2023 This article introduces a functional generalizing Perelman’s weighted Hilbert-Einstein action and the Dirichlet energy for spinors. It is well defined on a wide class of noncompact manifolds; on asymptotically Euclidean manifolds, the functional is shown

Eguchi–Hanson Singularities in U(2)-Invariant Ricci Flow [PDF]
Peking Mathematical Journal, 2019 We show that a Ricci flow in four dimensions can develop singularities modeled on the Eguchi–Hanson space. In particular, we prove that starting from a class of asymptotically cylindrical U (2)-invariant initial metrics on $$TS^2$$ T S 2 , a Type II ...

Malmö POTS symptom score: Assessing symptom burden in postural orthostatic tachycardia syndrome
Journal of Internal Medicine, Volume 293, Issue 1, Page 91-99, January 2023., 2023 Abstract Background Postural orthostatic tachycardia syndrome (POTS) is a common cardiovascular autonomic disorder characterized by excessive heart rate (HR) increase on standing and symptoms of orthostatic intolerance, posing significant limitations on functional capacity. No objective tool exists to classify symptom burden in POTS.

A note on conformal Ricci flow [PDF]
Pacific Journal of Mathematics, 2014 In this note we study conformal Ricci flow introduced by Arthur Fischer. We use DeTurck's trick to rewrite conformal Ricci flow as a strong parabolic-elliptic partial differential equations. Then we prove short time existences for conformal Ricci flow on compact manifolds as well as on asymptotically flat manifolds.

Investigating Structure and Agency in Chinese Indonesians' Identity Work
Journal of Linguistic Anthropology, Volume 32, Issue 3, Page 561-584, December 2022., 2022 Research shows that structure and agency are components of both micro and macro articulations of identity (Bucholtz and Hall, 2005). However, some scholars (e.g., Block 2013, 2015; Sealey and Carter 2004; Gao 2017) argue that structure and agency often receive unequal attention, with many studies focusing more on agency when examining identity work ...

Ricci Flow on Torus Bundles [PDF]
arXiv, 2021 In this paper we compute the Ricci flow formulas for invariant metrics on prinicpal $G$-bundles compatible with the connection. Our primary focus is on torus bundles which we use to study a notion of Bakry-\'Emery Ricci flow as well as Ricci flow on circle bundles over K\"ahler-Einstein manifolds.

Reduced ageing in the frozen state in the tardigrade Milnesium inceptum (Eutardigrada: Apochela)
Journal of Zoology, Volume 318, Issue 4, Page 253-259, December 2022., 2022 Tardigrades were subjected to subzero temperature treatment by cooling on agar plates from room temperature down to ‐30°C. The specimens were kept for seven days at ‐30°C without temperature fluctuations, after which the animals were allowed to slowly warm. Live and dead animals were recorded after thawing.
