Business Strategy and the Environment, EarlyView.ABSTRACT The transition to a circular economy (CE) has become a strategic priority for firms, yet empirical assessments of corporate circularity remain fragmented and heavily dependent on structured indicators or self‐reported metrics. This paper proposes a novel, text‐based circularity index derived from mandatory non‐financial statements of large ...

Regularising the Ricci Flow Embedding [PDF]
, 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.

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.

Stochastic Ricci Flow on Compact Surfaces [PDF]
, 2019 In this paper we introduce the stochastic Ricci flow (SRF) in two spatial dimensions. The flow is symmetric with respect to a measure induced by Liouville Conformal Field Theory.

Business Strategy and the Environment, EarlyView.ABSTRACT ESG ratings, and in particular environmental scores (E‐scores), are becoming increasingly relevant for financial stability and capital allocation decisions. This paper investigates the relationship between corporate environmental performance and market risk, as measured through value at risk (VaR) and expected shortfall (ES), the key metrics ...

Stability of piecewise flat Ricci flow in three dimensions
Journal of Numerical Analysis and Approximation TheoryFor a recently developed piecewise flat approximation of the Ricci flow, numerical instabilities are seen to arise for a particularly useful class of mesh-types.

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Research on digitalization, sustainability, and firm performance has grown rapidly in recent years, yet the literature remains fragmented across disciplines, concepts, and empirical settings. This study addresses the fragmentation by providing a combined bibliometric and systematic literature review (B‐SLR) of research at the intersection of ...

The Ricci flow for nilmanifolds
Journal of Modern Dynamics, 2010 We consider the Ricci flow for simply connected nilmanifolds, which translates to a Ricci flow on the space of nilpotent metric Lie algebras. We consider the evolution of the inner product and the evolution of structure constants, as well as the evolution of these quantities modulo rescaling.

A design tool for globally developable discrete architectural surfaces using Ricci flow
Japan Architectural Review, 2023 This paper presents an approach for the design of discrete architectural surfaces that are globally developable; that is, having zero Gaussian curvature at every interior node.
