Complete $(2+1)$-dimensional Ricci flow spacetimes [PDF]
, 2022 Ricci flow spacetimes were introduced by Kleiner & Lott as a way to describe Ricci flow through singularities, and have since been used elsewhere in the literature, prompting the question of their rigidity.

Lipidomics of orchid seeds: from development to storage
Plant Biology, EarlyView.The study tracked lipid changes from pollination to storage in two orchid species. Although both were desiccation‐tolerant and storable, differences in saturated and unsaturated fatty acid proportions during development led to different moisture contents and germination capacities.

Ricci flow on Courant algebroids [PDF]
We develop a theory of Ricci flow for metrics on Courant algebroids which unifies and extends the analytic theory of various geometric flows, yielding a general tool for constructing solutions to supergravity equations.

Stable Geodesic Surface Signatures
Tsinghua Science and Technology, 2012 Shape analysis plays a fundamental role in computer graphics. We present a novel global and intrinsic shape representation for shape analysis, called stable geodesic signature.

A Complexity‐Based Approach to Migration Policy Change: The Case of the German Residence Act
Regulation &Governance, EarlyView.ABSTRACT This paper adapts and applies existing indicators to measure the complexity of German migration policy over time. Building on recent scholarship that conceptualizes migration policy as multidimensional, I adapt a measurement strategy from the EUPLEX Project to capture three key components of regulatory complexity: structural, linguistic, and ...

Some Properties of Noncompact Ricci Solitons
AxiomsIn this article, we are interested in finding sufficient conditions for a noncompact Ricci soliton (M, h, v, λ) to be trivial. The major role is played by a skew-symmetric operator φ associated to the potential field v of the connected Ricci soliton (M ...

Mapping Organized Crime as a Stakeholder: A Risk‐Based and Responsive Governance Perspective
Regulation &Governance, EarlyView.ABSTRACT Organized crime (OC) can influence firms through coercion, collusion, financial ties, and supply‐chain relationships, yet these interactions remain underexamined in stakeholder theory. This article conceptualizes organized crime as an analytically relevant but non‐normatively legitimate stakeholder and develops a risk‐based framework combining

Sigma model renormalisation group flows, singularities and some remarks on cosmology
Physics Letters BWe investigate the properties of the renormalisation group (RG) flow of two-dimensional sigma models with a generic metric coupling by utilising known results for the Ricci flow. We point out that on many occasions the RG flow develops singularities, due
