On Almost Kenmotsu 3-Manifolds Which Are Conformally Flat
In this paper, we study conformally flat almost Kenmotsu 3-manifolds such that \(\text {tr} \, h^2\) is a constant and \(\nabla _{\xi }h=-2\alpha h\varphi \) for some constant \(\alpha \). Moreover, we classify conformally flat H-almost Kenmotsu 3-manifolds.
期刊介绍：
The Mediterranean Journal of Mathematics (MedJM) is a publication issued by the Department of Mathematics of the University of Bari. The new journal replaces the Conferenze del Seminario di Matematica dell’Università di Bari which has been in publication from 1954 until 2003.
The Mediterranean Journal of Mathematics aims to publish original and high-quality peer-reviewed papers containing significant results across all fields of mathematics. The submitted papers should be of medium length (not to exceed 20 printed pages), well-written and appealing to a broad mathematical audience.
In particular, the Mediterranean Journal of Mathematics intends to offer mathematicians from the Mediterranean countries a particular opportunity to circulate the results of their researches in a common journal. Through such a new cultural and scientific stimulus the journal aims to contribute to further integration amongst Mediterranean universities, though it is open to contribution from mathematicians across the world.
