Pseudolocality for the Ricci Flow and Applications [PDF]
Canadian Journal of Mathematics, 2011 Abstract Perelman established a differential Li-Yau-Hamilton (LYH) type inequality for fundamental solutions of the conjugate heat equation corresponding to the Ricci flow on compact manifolds. As an application of the LYH inequality, Perelman proved a pseudolocality result for the Ricci flow on compact manifolds. In this article we provide the details

Archaeological Prospection, EarlyView.ABSTRACT This study presents a multi‐method non‐invasive investigation of an approximately 4‐ha area associated with the long‐occupied coastal settlement of Rocavecchia (Apulia, southern Italy), situated between the prehistoric fortified peninsula and the Hellenistic‐Messapian walls.

Entropy of Reissner–Nordström 3D Black Hole in Roegenian Economics
Entropy, 2019 The subject of this paper is to analyse the Mathematical Principia of Economic 3D Black Holes in Roegenian economics. In detail, we study two main problems: (i) mathematical origin of economic 3D black holes; and (ii) entropy and internal political ...

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 ...

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.

Management of ring chromosome 20 syndrome: Narrative review and consensus recommendations
Epilepsia, EarlyView.Abstract Ring chromosome 20 (ring 20) is a rare genetic condition usually presenting as developmental and epileptic encephalopathy. The disease is caused by fusion of the long and short arms of chromosome 20. Patients are symptomatic even if there is no loss of genetic material.

Journal of Applied Toxicology, EarlyView.ABSTRACT Three new Zn (II), Cu (II) and Mn (II) complexes have been synthesized from 5‐hydroxy‐1,4‐naphthoquinone (HNQ). Elemental analysis, magnetic susceptibility, UV–Vis, IR and Mass spectrometry have all been used to explore the structural characterization of these compounds.

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.
