<p>[02:03:14] Putting these two elliptic complexes together, the Dirac terms go between the two complexes, right? So the idea is that the stress energy tensor should be the up-and-back term and the Dirac equations should come out of the term that goes up-and-over versus the term that goes over-and-up, and you need some cancellations to make sure that everything is of zeroth-order, properly invariant, etc. | <p>[02:03:14] Putting these two elliptic complexes together, the Dirac terms go between the two complexes, right?

<p>[02:03:39] And that's taking a little time because frankly, I'm not good at keeping track of indices minus signs left | <p>[02:03:39] And that's taking a little time because frankly, I'm not good at keeping track of indices minus signs left-right? That it's a learning-disabled nightmare. | ||
<p>[02:03:53] So | <p>[02:03:53] So, we've got one more unit to go. I mean, there's a fifth unit that has to do with mathematical applications, but this is sort of a physics talk for today. Is there any questions before we go into the last unit and then really handle questions for real? All right, let me show you the next little bit. | ||
