Finite extinction time for the solutions to the Ricci flow on certain three-manifolds [PDF]
, 2003 Let M be a closed oriented three-manifold, whose prime decomposition contains no aspherical factors. We show that for any initial riemannian metric on M the solution to the Ricci flow with surgery, defined in our previous paper math.DG/0303109, becomes ...

The Effects of Regulatory Office Closures on Bank Behavior
Journal of Money, Credit and Banking, EarlyView.Abstract We investigate if the decentralized structure of regulatory office networks influences supervisory outcomes and bank behavior. Following the closure of an office, banks previously supervised by that office increase their lending and risk‐taking.

On Pseudo Cyclic Ricci Symmetric Manifolds
Süleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2011 : The object of the present paper is to study concircularly symmetric (PCRS)n, concircularly recurrent (PCRS)n, decomposable (PCRS)n. Among others it is shown that in a decomposable (PCRS)n one of the decompositions is Ricci flat and the other ...

Isoparametric foliation and a problem of Besse on generalizations of Einstein condition [PDF]
, 2015 The focal sets of isoparametric hypersurfaces in spheres with g = 4 are all Willmore submanifolds, being minimal but mostly non-Einstein ([TY1], [QTY]).

The Dirichlet Problem for Einstein Metrics on Cohomogeneity One Manifolds
, 2017 Let $G/H$ be a compact homogeneous space, and let $\hat{g}_0$ and $\hat{g}_1$ be $G$-invariant Riemannian metrics on $G/H$. We consider the problem of finding a $G$-invariant Einstein metric $g$ on the manifold $G/H\times [0,1]$ subject to the constraint

A complex network perspective on brain disease
Biological Reviews, Volume 101, Issue 1, Page 364-399, February 2026.ABSTRACT If brain anatomy and dynamics have a complex network structure as it has become standard to posit, it is reasonable to assume that such a structure should play a key role not only in brain function but also in brain dysfunction. However, exactly how network structure is implicated in brain damage and whether at least some pathologies can be ...

EFSA Journal, Volume 24, Issue 2, February 2026.Abstract EFSA has received a request for a rapid risk assessment for cereulide from the European Commission. Cereulide is a heat‐stable emetic toxin produced by Bacillus cereus, recently detected in infant formulae from multiple manufacturers. This led to precautionary recalls across several countries.

Ricci iteration for coupled K\"ahler-Einstein metrics
, 2019 In this paper, we introduce the "coupled Ricci iteration", a dynamical system related to the Ricci operator and twisted K\"ahler-Einstein metrics as an approach to the study of coupled K\"ahler-Einstein (CKE) metrics.

Annalen der Physik, Volume 538, Issue 1, January 2026.The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,
