Title |
Atiyah classes for global matrix factorizations |
Abstract |
This is a joint work with Bumsig Kim. We define the notion of Atiyah class for global matrix factorization and use it to calculate the categorical Chern character. The key role is played by the analog in this context of the Lie algebra structure on the shifted tangent bundle defined and studied by Kapranov and Markarian. |
