Hamiltonian actions on 0-shifted cosymplectic groupoids
Daniel López Garcia, Fabricio Valencia
We introduce the notion of 0-shifted cosymplectic structure on differentiable stacks and develop a corresponding moment map theory for Hamiltonian cosymplectic actions. We present…

Topology of singular foliations of closed 1-forms on orbifolds
Daniel Lopez Garcia, Fabricio Valencia
We study the topological properties of the leaves of the singular foliation induced by a closed 1-form of Morse type on a compact orbifold. In particular, we establish criteria tha…

Double extension of flat pseudo-Riemannian -Lie algebras
Alexander Torres-Gomez, Fabricio Valencia
We define the concept of a flat pseudo-Riemannian -Lie algebra and construct its corresponding double extension. This algebraic structure can be interpreted as the infinitesimal…
