# Projectivity in Algebraic Cobordism

@article{LuisGonzalez2013ProjectivityIA, title={Projectivity in Algebraic Cobordism}, author={Jose Luis Gonzalez and Kalle Karu}, journal={Canadian Journal of Mathematics}, year={2013}, volume={67}, pages={639 - 653} }

Abstract The algebraic cobordism group of a scheme is generated by cycles that are proper morphisms from smooth quasiprojective varieties. We prove that over a field of characteristic zero the quasiprojectivity assumption can be omitted to get the same theory.

We prove the exactness of a descent sequence relating the algebraic cobordism groups of a scheme and its envelopes. Analogous sequences for Chow groups and K-theory were previously proved by Gillet.
