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.

Bi-slant submanifolds of para Hermitian manifolds
(MDPI, 2019-07-11)In this paper, we introduce the notion of bi-slant submanifolds of a para Hermitian manifold. They naturally englobe CR, semi-slant, and hemi-slant submanifolds. We study their first properties and present a whole gallery of examples.

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.
