   Format: MarkdownItexadded ([here](https://ncatlab.org/nlab/show/Todd+class#RationalToddClassIsChernCharacterOfThomClass)) the statement that the [[rational Todd class is Chern character of Thom class]]. Will also give this statement a little stand-alone entry now, for ease of cross-referencing with _[[Chern character]]_, _[[Thom class]]_, etc. <a href="https://ncatlab.org/nlab/revision/diff/Todd+class/9">diff</a>, <a href="https://ncatlab.org/nlab/revision/Todd+class/9">v9</a>, <a href="https://ncatlab.org/nlab/show/Todd+class">current</a>

   added (here) the statement that the rational Todd class is Chern character of Thom class.

   Will also give this statement a little stand-alone entry now, for ease of cross-referencing with Chern character, Thom class, etc.
