spelling. Either Kähler or Kaehler is correct (those two are by standard convention equivalent) but if it were Kahler, it would be pronounced differently.

| Jun 12, 2020 at 14:31 | comment | added | Qfwfq | @amathematician: fair enough | |
| Jun 12, 2020 at 13:47 | comment | added | amathematician | @Qfwfq The applications in the papers of Lazaroiu et al are to string theory and supergravity, though the wider approach which they develop works for many other problems in spin geometry and spinorial global analysis. "Geometric algebra" is a topic in the theory of Clifford bundles, which is itself a subject in ordinary spin geometry. As shown in the papers I mentioned, it is a rich subject which provides computationally and conceptually useful perspectives on certain problems but it is not a separate or new theory in mathematics. Lazaroiu et al are very clear on that point. | |

I haven't read through anything at all, but my impression was that the two answers (present so far) deal with string theory and supergravity, while the work of Hestenes et al. only involves general relativity and classical mechanics. Was my impression inaccurate? | |

Minor typos and Jaxing

| Jun 12, 2020 at 1:00 | comment | added | Qfwfq | Ok so this, like in the above answer by AlexArvanitakis, is another context in which Clifford/geometric algebras appear, of which I wasn't aware. Thank you both for your answers. | |
