Segal's 1965 <a href="http://www.ams.org/journals/bull/1965-71-03/S0002-9904-1965-11284-8/S0002-9904-1965-11284-8.pdf" rel="nofollow">Algebraic integration theory</a> is also a good place to look; he walks you through for example how to view a measure space as a "spectrum" of an algebra of random variables (e.g. the unnumbered theorem on page 432).</p> http://mathoverflow.net/questions/42929/suggestions-for-good-notation/42995#42995 Answer by Jason Morton for Suggestions for good notation Jason Morton 2010-10-21T03:21:37Z 2010-10-21T03:21:37Z <p>Diagrammatic notation for tensors (Penrose diagrams, birdtracks, etc.). It makes many things like the invariance of tr(A B C) under cyclic permutation into empty statements.</p>
