# A note on coherent orientations for exact Lagrangian cobordisms

@article{Karlsson2019ANO, title={A note on coherent orientations for exact Lagrangian cobordisms}, author={Cecilia Karlsson}, journal={Quantum Topology}, year={2019} }

Let $L \subset \mathbb R \times J^1(M)$ be a spin, exact Lagrangian cobordism in the symplectization of the 1-jet space of a smooth manifold $M$. Assume that $L$ has cylindrical Legendrian ends $\Lambda_\pm \subset J^1(M)$. It is well known that the Legendrian contact homology of $\Lambda_\pm$ can be defined with integer coefficients, via a signed count of pseudo-holomorphic disks in the cotangent bundle of $M$. It is also known that this count can be lifted to a mod 2 count of pseudo…
