Split Canonical Relations
Alberto S. Cattaneo, Ivan Contreras
A Lagrangian subspace of a weak symplectic vector space is called \emph{split Lagrangian} if it has an isotropic (hence Lagrangian) complement. When the symplectic structure is…
Gluing of Graph Laplacians and Their Spectra
Ivan Contreras, Michael Toriyama, Chengzheng Yu
We study two different types of gluing for graphs: interface (obtained by choosing a common subgraph as the gluing component) and bridge gluing (obtained by adding a set of edges t…
Genus Integration, Abelianization and Extended Monodromy
Ivan Contreras, Rui Loja Fernandes
Given a Lie algebroid we discuss the existence of a smooth abelian integration of its abelianization. We show that the obstructions are related to the extended monodromy groups int…
Kähler fibrations in quantum information theory
Ivan Contreras, Michele Schiavina
We discuss the fibre bundle of co-adjoint orbits of compact Lie groups, and show how it admits a compatible Kähler structure. The case of the unitary group allows us to reformulate…
