Is there a common general setup for both Weil cohomologies and generalized cohomology theories? - MathOverflow most recent 30 from http://mathoverflow.net2013-06-19T14:21:41Zhttp://mathoverflow.net/feeds/question/61604http://www.creativecommons.org/licenses/by-nc/2.5/rdfhttp://mathoverflow.net/questions/61604/is-there-a-common-general-setup-for-both-weil-cohomologies-and-generalized-cohomoIs there a common general setup for both Weil cohomologies and generalized cohomology theories?Qfwfq2011-04-13T22:58:06Z2011-04-13T23:14:28Z
<p>My question can be simply (and loosely) stated as follows:</p>
<blockquote>
<p>Is there a general (but not <em>too</em> general) construction that captures, as specializations, both Weil cohomologies in algebraic geometry and generalized cohomology theories in topology ?</p>
</blockquote>
<p>(I must say I'm not an expert of any of the two!)</p>

However, Voevodsky's motivic homotopy theory does provide an adequate framework for both Weil cohomologies and generalized cohomology theories; there is a version of "Brown representability" theorem (representing object for a generalized cohomology theory) which is exploited in the applications to K-theory (Milnor conjecture and Bloch-Kato conjecture). </p>
