Sigma model renormalisation group flows, singularities and some remarks on cosmology

Physics Letters B
We 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

Collapsing immortal Kähler-Ricci flows

Forum of Mathematics, Pi
We consider the Kähler-Ricci flow on compact Kähler manifolds with semiample canonical bundle and intermediate Kodaira dimension, and show that the flow collapses to a canonical metric on the base of the Iitaka fibration in the locally smooth topology ...

Generalized Sasakian Space-Forms with Beta-Kenmotsu Structure and Ricci Solitons [PDF]

International Journal of Mathematical, Engineering and Management Sciences
We explore the properties of almost Ricci solitons and the gradient Ricci solitons on generalized Sasakian-space-forms with beta-Kenmotsu structure. We consider almost Ricci solitons on generalized Sasakian-space-forms with beta-Kenmotsu structure when ...

Singularities of Connection Ricci Flow and Ricci Harmonic Flow

, 2013
In this paper, we study the singularities of two extended Ricci flow systems --- connection Ricci flow and Ricci harmonic flow using newly-defined curvature quantities. Specifically, we give the definition of three types of singularities and their corresponding singularity models, and then prove the convergence. In addition, for Ricci harmonic flow, we

Building a Robust Investigator‐Initiated Platform: The I‐CARE Experience

Clinical Pharmacology &Therapeutics, Volume 119, Issue 6, Page 1537-1546, June 2026.
Investigator‐initiated studies that include information collected by patients are rising, but limited data is available on patient and investigator experience in this setting. The I‐CARE cohort included patients with inflammatory bowel disease (IBD) monthly collecting clinical information in 15 countries for up to 6 years.

Non-local interaction in discrete Ricci curvature-induced biological aggregation

Royal Society Open Science
We investigate the collective dynamics of multi-agent systems in two- and three-dimensional environments generated by minimizing discrete Ricci curvature with local and non-local interaction neighbourhoods.

Forman-Ricci Flow for Change Detection in Large Dynamic Data Sets

Axioms, 2016
We present a viable geometric solution for the detection of dynamic effects in complex networks. Building on Forman’s discretization of the classical notion of Ricci curvature, we introduce a novel geometric method to characterize different types of real-
