Morse–Bott theory on posets and a homological Lusternik–Schnirelmann theorem
(World Scientific Publishing Company, 2021)We develop Morse–Bott theory on posets, generalizing both discrete Morse–Bott theory for regular complexes and Morse ...

A closed form for slant submanifolds of generalized Sasakian space forms
(MDPI, 2019-12-13)The Maslov form is a closed form for a Lagrangian submanifold of Cm, and it is a conformal form if and only if M satisfies ...

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.

Polynomial braid combing
(Oxford University Press, 2018)We prove that, for n ≥ 3, the minimal dimension of a model of the classifying space of the braid group Bn, and of the pure braid group Pn, with respect to the family of virtually cyclic groups is n.

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.
