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 ...

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.

Ricci Flow and Volume Renormalizability [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2019 With respect to any special boundary defining function, a conformally compact asymptotically hyperbolic metric has an asymptotic expansion near its conformal infinity. If this expansion is even to a certain order and satisfies one extra condition, then it is possible to define its renormalized volume and show that it is independent of choices that ...

Modified Ricci flow on a principal bundle [PDF]
, 2008 textLet M be a Riemannian manifold with metric g, and let P be a principal G-bundle over M having connection one-form a. One can define a modified version of the Ricci flow on P by fixing the size of the fiber.

Existence of Ricci flows of incomplete surfaces [PDF]
, 2011 We prove a general existence result for instantaneously complete Ricci flows starting at an arbitrary Riemannian surface which may be incomplete and may have unbounded curvature.

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 ...

Journal of MathematicsIn this paper, we investigate the geometric properties of η-Ricci–Bourguignon (η-RB) solitons on para-Sasakian manifolds equipped with a semisymmetric nonmetric connection (SSNMC). By employing the complete lift on the tangent bundle, we derive curvature

Drivers of Sustainability Disclosure in the Healthcare Sector: Empirical Evidence From Portugal
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study examines the determinants of online sustainability disclosure in the Portuguese public hospital sector, contributing to the growing literature on sustainability disclosure in healthcare organizations from a context that remains largely underexplored.

On non-degenerate singular points of normalized Ricci flows on some generalized Wallach spaces
Қарағанды университетінің хабаршысы. Математика сериясы, 2015 The present paper devoted to problems of Riemannian geometry and planar dynamical systems. In particular we study nondegenerate singular points of normalized Ricci flows on special type of generalized Wallach spaces.

Metric flows with neural networks
Machine Learning: Science and TechnologyWe develop a general theory of flows in the space of Riemannian metrics induced by neural network (NN) gradient descent. This is motivated in part by recent advances in approximating Calabi–Yau metrics with NNs and is enabled by recent advances in ...
