Trans-Sasakian 3-Manifolds with Reeb Flow Invariant Ricci Operator
Mathematics, 2018 Let M be a three-dimensional trans-Sasakian manifold of type ( α , β ) . In this paper, we obtain that the Ricci operator of M is invariant along Reeb flow if and only if M is an α -Sasakian manifold, cosymplectic manifold or a

Fractional nonholonomic Ricci flows [PDF]
Chaos, Solitons & Fractals, 2012 We formulate the fractional Ricci flow theory for (pseudo) Riemannian geometries enabled with nonholonomic distributions defining fractional integro-differential structures, for non-integer dimensions. There are constructed fractional analogs of Perelman's functionals and derived the corresponding fractional evolution (Hamilton's) equations.

Diversity and Prevalence of Coral Diseases in the Nearshore Regions of the Northern South China Sea
Ecology and Evolution, Volume 15, Issue 12, December 2025.This study presents the first systematic survey of coral disease diversity and prevalence in the nearshore regions of the northern South China Sea. Six common diseases and eight stress‐related phenomena were documented across seven sites, revealing distinct regional patterns and host‐specific susceptibilities.

The Ricci flow on the 2-sphere
Journal of Differential Geometry, 1991 The classical uniformization theorem, interpreted differential geomet-rically, states that any Riemannian metric on a 2-dimensional surface ispointwise conformal to a constant curvature metric. Thus one can con-sider the question of whether there is a natural evolution equation whichconformally deforms any metric on a surface to a constant curvature ...

MicrobiologyOpen, Volume 14, Issue 6, December 2025.National survey of 18,747 Tanzanians reveals malaria knowledge disparities by age, education, gender, and residence. Urban, educated, and media‐exposed individuals showed higher awareness, while rural and older populations lagged. Targeted education, digital tools, and rural infrastructure improvements are vital to closing gaps and strengthening ...
