<p>Please feel free to make suggestions in this thread as to how the format and organisation of these projects (or this blog) could be improved.</p>

			<content:encoded><![CDATA[<p>This is a mock-up of what a research thread for a polymath project would look like.  The thread would begin with a statement of the research problem, e.g.</p>
<blockquote><p><strong>Problem (Boundedness of the trilinear Hilbert transform).</strong> Show that the trilinear Hilbert transform <img src='http://s0.wp.com/latex.php?latex=T%28f%2Cg%2Ch%29+%3A%3D+p.v.+%5Cint_%7B-%5Cinfty%7D%5E%5Cinfty+f%28x%2Bt%29+g%28x%2B2t%29+h%28x%2B3t%29+%5Cfrac%7Bdt%7D%7Bt%7D&amp;bg=ffffff&amp;fg=000000&amp;s=0' alt='T(f,g,h) := p.v. &#92;int_{-&#92;infty}^&#92;infty f(x+t) g(x+2t) h(x+3t) &#92;frac{dt}{t}' title='T(f,g,h) := p.v. &#92;int_{-&#92;infty}^&#92;infty f(x+t) g(x+2t) h(x+3t) &#92;frac{dt}{t}' class='latex' /> is bounded from <img src='http://s0.wp.com/latex.php?latex=L%5E%7Bp_1%7D%28%7B%5CBbb+R%7D%29+%5Ctimes+%5Cldots+%5Ctimes+L%5E%7Bp_3%7D%28%7B%5CBbb+R%7D%29+%5Cto+L%5Ep%28%7B%5CBbb+R%29%7D&amp;bg=ffffff&amp;fg=000000&amp;s=0' alt='L^{p_1}({&#92;Bbb R}) &#92;times &#92;ldots &#92;times L^{p_3}({&#92;Bbb R}) &#92;to L^p({&#92;Bbb R)}' title='L^{p_1}({&#92;Bbb R}) &#92;times &#92;ldots &#92;times L^{p_3}({&#92;Bbb R}) &#92;to L^p({&#92;Bbb R)}' class='latex' /> for some <img src='http://s0.wp.com/latex.php?latex=p_1%2Cp_2%2Cp_3%2Cp&amp;bg=ffffff&amp;fg=000000&amp;s=0' alt='p_1,p_2,p_3,p' title='p_1,p_2,p_3,p' class='latex' /> (e.g. <img src='http://s0.wp.com/latex.php?latex=p_1%3Dp_2%3Dp_3%3D4&amp;bg=ffffff&amp;fg=000000&amp;s=0' alt='p_1=p_2=p_3=4' title='p_1=p_2=p_3=4' class='latex' /> and <img src='http://s0.wp.com/latex.php?latex=p_4+%3D+4%2F3&amp;bg=ffffff&amp;fg=000000&amp;s=0' alt='p_4 = 4/3' title='p_4 = 4/3' class='latex' />).</p></blockquote>
<p>Some discussion of the precise objective (are we aiming for an actual proof, or would we be happy with understanding why the problem is difficult?) would go here.  [Note: while the above problem is an important open problem in harmonic analysis, I am not actually proposing to solve it by polymath here; it is only being used as an example for the purposes of this mock-up.]</p>
<p>A brief discussion of prior results would also be appropriate here, though an extended bibliography might be better placed on <a href="http://michaelnielsen.org/polymath1/index.php?title=Main_Page">the wiki</a>.</p>
<p>A reminder of the <a href="http://polymathprojects.wordpress.com/general-polymath-rules/">polymath rules</a> might also be placed here, together with a link to <a href="http://michaelnielsen.org/polymath1/index.php?title=Main_Page">the discussion thread</a> for issues relating to exposition, strategy, and other meta-comments.  The initiator of the project should also put some effort into laying down preliminary thoughts of the project as clearly as possible.</p>
<p>All threads in a polymath project would have a dedicated category; in this case, the category is <a href="http://polymathprojects.wordpress.com/category/mock-up/">mock-up</a>.</p>
<p>Finally, one should put a list of moderators of the project, who would be able to respond to technical issues, such as fixing up a mangled comment.  For this mock-up project, the moderators are:</p>
<ul>
<li>Terence Tao (tao@math.ucla.edu)</li>
