A contact version of B.-Y. Chen's inequality and its applications to slant immersions
(Kyungpook National University, 1999)We establish a version of B.-Y. Chen’s inequality for a submanifold of a Sasakianspace-form, tangent to the structure ...

A historical perspective of the theory of isotopisms
(MDPI, 2018-08-03)In the middle of the twentieth century, Albert and Bruck introduced the theory of isotopisms of non-associative algebras ...

Almost cosymplectic and almost Kenmotsu (κ, μ, ν)-spaces
(Springer, 2013-08)We study the Riemann curvature tensor of (κ, µ, ν)-spaces when they have almost cosymplectic and almost Kenmotsu structures, ...

B.-Y. Chen's inequality for submanifolds of generalized space forms
(Indian National Science Academy, 2007-06)In this article, we investigate sharp inequalities involving δ-invariants for submanifolds in both generalized complex space forms and generalized Sasakian space forms, with arbitrary codimension.

Bochner and conformal flatness on normal complex contact metric manifolds
(Springer, 2010-10-10)We will prove that normal complex contact metric manifolds that are Bochner flat must have constant holomorphic sectional ...

Cellular covers of local groups
(Springer, 2018-12)We prove that, in the category of groups, the composition of a cellularization and a localization functor need not be idempotent. This provides a negative answer to a question of Emmanuel Dror Farjoun.

Generalized (κ,μ)-space forms
(Springer, 2013-02)Generalized (κ, µ)-space forms are introduced and studied. We examine in depth the contact metric case and present examples for all possible dimensions. We also analyse the trans-Sasakian case.

On pseudo-Einstein hypersurfaces of ℋ2n+s
(Indian National Science Academy, 1996-05)In this paper, some properties of the geometry of pseudo-Einstein hypersurfaces of the S-manifold ℋ 2n+s are studied and a theorem concerning their principal curvatures is obtained.
