Álvaro del Pino, Aldo Witte
We describe a procedure, called regularisation, that allows us to study geometric structures on Lie algebroids via foliated geometric structures on a manifold of higher dimension.…

Classification of Engel Knots
Roger Casals, Álvaro del Pino
For any Engel 4-fold, we show that the scanning map from the space of Engel knots to the space of formal Engel knots is a weak homotopy equivalence when restricted to the complemen…
