Abstract

This is a sequel to our previous paper of oriented bivariant theory [14]. In 2001 M. Levine and F. Morel constructed algebraic cobordism Ω(X)\Omega_*(X) for schemes XX over a field kk in an abstract way and later M. Levine and R. Pandhairpande reconstructed it more geometrically. In this paper in a similar manner we construct an algebraic cobordism Ω(XπXS)\Omega^*(X \xrightarrow {\pi_X} S) for a scheme XX over a fixed scheme SS in such a way that if the target scheme SS is the point pt=Speckpt = \operatorname{Spec} k, then Ωi(XπXpt)\Omega^{-i}(X \xrightarrow {\pi_X} pt) is isomorphic to Levine-Morel's algebraic cobordism Ωi(X)\Omega_i(X)
