2020 Mathematics Subject Classification: Primary: 57R20 [MSN][ZBL]
A characteristic class of a complex bundle $\zeta$, equal to
$$\sum_{j=0}^\infty T_j(c_1,\dots,c_j),$$
where $\{T_j\}$ is the sequence of Todd polynomials, defined by the multiplicative sequence corresponding to the power series $t/(1-e^{-t})$ and $c_i$ are the Chern classes.
Introduced by J. Todd [1].
