Collapsing immortal Kähler-Ricci flows

open access: yesForum 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 ...

Regularising the Ricci Flow Embedding [PDF]

open access: yes, 2010
This paper concerns the analysis of patterns that are specified in terms of non-Euclidean dissimilarity or proximity rather than ordinal values. In prior work we have reported a means of correcting or rectifying the similarities so that the non-Euclidean artifacts are minimized.

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

open access: yesAxioms, 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-

Combinatorial Ricci Flows on Surfaces

open access: yesJournal of Differential Geometry, 2003
We show that the analog of Hamilton's Ricci flow in the combinatorial setting produces solutions which converge exponentially fast to Thurston's circle packing on surfaces. As a consequence, a new proof of Thurston's existence of circle packing theorem is obtained. As another consequence, Ricci flow suggests a new algorithm to find circle packings.

Embracing new practices in plant breeding for agroecological transition: A diversity‐driven research agenda

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 38-48, January 2026.
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 ...
