Abstract

This paper deals with the question of J.Morava on existence of canonical complex cobordism class of singular submanifold. We present several solutions of this question for $X_r(\xi)$ -- the set of points where $\dim\xi-r+1$ generic sections of a complex vector bundle $\xi$ are linearly dependent. The corresponding complex cobordism classes $Q_r(\xi)$ and $P_r(\xi)$ tend to have many nice properties, such as deformed sum formula, but they don't coincide with Chern classes $c_r^U(\xi)$. They also have relation to the theory of $IH$-small resolutions.
