title: Latex Math Symbol: Vitanyi puts a tiny plus symbol over his equals. How do I do that?
body: <p>For example, in <a href="http://homepages.cwi.nl/~paulv/papers/algorithmicstatistics.pdf" rel="noreferrer">http://homepages.cwi.nl/~paulv/papers/algorithmicstatistics.pdf</a> at the bottom of page 5 and top of page 6, he uses a plus/equal symbol and a similar plus/lessthan symbol.  I can't figure out how to make that symbol, and I'd like to quote him.</p>
  
  <p>Any help?</p>
