$b^{k}$ -algebroids and the variety of foliation jets

Francis Bischoff, Álvaro del Pino, Aldo Witte

We introduce and classify singular foliations of $b^{k + 1}$ -type, which formalize the properties of vector fields that are tangent to a submanifold $W \subset M$ to order $k$ . When…

Thin homotopy and the signature of piecewise linear surfaces

Francis Bischoff, Darrick Lee

We introduce a crossed module of piecewise linear surfaces and study the signature homomorphism, defined as the surface holonomy of a universal translation invariant $2$ -connection…
