Alexander Cardona is an Associate Professor in the Mathematics Department at Universidad de los Andes, Colombia. His research activity concerns mathematical tools that are motivated by physical problems. He studies differential geometry and global analysis, and their applications to physical models in which the underlying topology is important.Andrés F. Reyes-Lega is an Associate Professor in the Physics Department at Universidad de los Andes, Colombia. His research contributions include studies on the algebraic structures underpinning quantum entanglement, the interplay between geometry, topology, and physics and mathematical aspects of quantum field theory.
