The necessary conditions for A (k, µ)-Paracontact space to be η-EINST EIN manifold

, 2022
The object of this paper is to study the curvature tensors of (k, µ)-Paracontact manifold satisfying the conditions R(X, Y) · C = 0, ˜Z(X, Y) · C = 0 and C(X, Y) · C = 0. According these cases, (k, µ)-Paracontact manifolds have been characterized such as

Characterization on N(k)-Mixed Quasi-Einstein Manifold

, 2019
[[abstract]]In the present paper we study characterizations of odd and even dimensional N(k)-mixed quasi-Einstein manifold and finally prove that a N(k)-mixed quasi-Einstein manifold is a semi mixed quasi- Einstein manifold under a certain condi ...

Some results of η-Ricci solitons on (LCS)n-manifolds [PDF]

Surveys in Mathematics and its Applications, 2018
In this paper, we consider an η -Ricci soliton on the (LCS)n-manifolds (M, φ , ξ , η , g) satisfying certain curvature conditions likes: R(ξ , X) · S= 0 and W 2(ξ, X) · S=0.

Janus Photonic Graphics by Stratified Assembly of Two Distinct Colloids

Advanced Functional Materials, Volume 36, Issue 53, 2 July 2026.
Double‐sided Janus photonic micropatterns with vivid structural colors are fabricated through a single‐step bottom‐up strategy. Density‐driven stratification and depletion‐mediated crystallization of PMMA and PS binary colloids lead to exclusive lattices on opposite surfaces under centrifugal force.

f– Kenmotsu Metric as Conformal Ricci Soliton

Annals of the West University of Timisoara: Mathematics and Computer Science, 2017
In this paper, we study conformal Ricci solitons in f- Kenmotsu manifolds. We derive conditions for f-Kenmotsu metric to be a conformal Ricci soliton.

Ομογενείς μετρικές Einstein σε γενικευμένες πολλαπλότητες σημαιών

, 2011
Μια πολλαπλότητα Riemann (M, g) ονομάζεται Einstein αν έχει σταθερή καμπυλότητα Ricci. Είναι γνωστό ότι αν (M=G/K, g) είναι μια συμπαγής ομογενής πολλαπλότητα Riemann, τότε οι G-αναλλοίωτες μετρικές Einstein μοναδιαίου όγκου, είναι τα κρίσιμα ...

Pair of Associated η-Ricci–Bourguignon Almost Solitons with Vertical Potential on Sasaki-like Almost Contact Complex Riemannian Manifolds

Mathematics
The manifolds studied are almost contact complex Riemannian manifolds, known also as almost contact B-metric manifolds. They are equipped with a pair of pseudo-Riemannian metrics that are mutually associated to each other using an almost contact ...

On the orientability of the asset equilibrium manifold [PDF]

This paper addresses partly an open question raised in the Handbook of Mathematical Economics about the orientability of the pseudo-equilibrium manifold in the basic two-period General Equilibrium with Incomplete markets (GEI) model. For a broad class of
