On N(k)-Contact Metric Manifolds

Abstract: The object of the present paper is to study a type of contact metric manifolds, called N (k)-contact metric manifolds admitting a non-null concircular and torse forming vector field. Among others it is shown that such a manifold is either locally isometric to the Riemannian product E n+1 (0) × S n (4) or a Sasakian manifold. Also it is shown that such a contact metric manifold can be expressed as a warped product I×ep * M , where ( * M , * g ) is a 2n-dimensional manifold.

“…Inhalation of dust over periods of time leads to proliferation of alveolar epithelium and fibrotic changes in lungs [11][12][13]15]. Severity depends on several factors including chemical nature, physical state of inhaled substance, size, concentration of dust particles, duration of exposure and individual susceptibility.…”

“…By extending the notion of local φ-symmetry of Takahashi [7], De et al [8] introduced and studied the notion of φ-recurrent Sasakian manifold. It may be mentioned that locally φ-symmetric and φ-recurrent LP-Sasakian, (LCS) n and (k, µ)-contact metric manifolds are respectively studied in [9][10][11][12][13].…”
