ON GENERALIZED (σ,ι)-DERIVATIONS Ⅱ
Raluca Mocanu,Hulya G. Inceboz 대한수학회 2010 대한수학회지 Vol.47 No.3
This paper continues a line investigation in [1]. Let A be a K-algebra and M an A/K-bimodule. In [5] Hamaguchi gave a necessary and sufficient condition for gDer(A,M) to be isomorphic to BDer(A,M). The main aim of this paper is to establish similar relationships for generalized (σ,ι)-derivations.
GRAY CURVATURE IDENTITIES FOR ALMOST CONTACT METRIC MANIFOLDS
Mocanu, Raluca,Munteanu, Marian Ioan Korean Mathematical Society 2010 대한수학회지 Vol.47 No.3
Alfred Gray introduced in [8] three curvature identities for the class of almost Hermitian manifolds. Using the warped product construction and the Boothby-Wang fibration we will give an equivalent of these identities for the class of almost contact metric manifolds.
